Remove some action which were writing scan bit to scoreboard,
since these behaviors are redundant.
It is already done in WLAN info notify.

Force set the coexistence to BT high priority during
WLAN initial/power-on step. Since the duration the related setting
may be not ready yet.
The score board is not related to scan when initialing, remove the scan
parameter.

While the mechanism goes to 2G_free_run or WL5G_BT2G,
set BT to hardware PTA mode to get a more efficiently performance.

The updated parameter and original parameter all means TDMA-OFF.
The original setting write 0x8 to firmware, but it only works for
some old IC series.
To avoid the confusing, update a proper parameter.

When WLAN in critical procedure, such as connecting, scan and so on,
coexistence will notify BT by scoreboard.
While BT firmware received the scoreboard interrupt, it will adjust

Life time related setting is related to WLAN active port number,
not its mode. The original setting may cause poor WLAN performance.
In most case, WLAN TX limitation is helpful for BT in coexistence
scenario, especially for A2DP quality.
So this is necessary to fix the setting and constraint it.

Add counter to count BT info C2H command for debug usage.
It could present the C2H channel situation.
Fix BT IQK state decision condition for counting.
The original condition is wrong, it would cause coexistence mechanism
going to the wrong strategy.
New format supports getting TDMA parameter from WL firmware, since
coexistence needs current TDMA parameter to decide strategy.
Remove unnecessary operations about scoreboard, it is not a must for
current version.

Some register definition and bit definition were incorrect.
e.g. REG_BT_COEX_V2 should be word alignment to meet the coding style.
e.g. set REG_BT_TDMA_TIME[5:0]=0x5,
But the original is to set REG_BT_TDMA_TIME[7:0]=0x5.
This will cause unexpected hardware behavior.

halbtc_send_bt_mp_operation() uses in_interrupt() to determine if it is
safe to invoke wait_for_completion().
The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.
Aside of that in_interrupt() is not correct as it does not catch preempt
disabled regions which neither can sleep.
halbtc_send_bt_mp_operation() is called from:
rtl_watchdog_wq_callback()
rtl_btc_periodical()
halbtc_get()
case BTC_GET_U4_BT_PATCH_VER:
halbtc_get_bt_patch_version()
which is preemtible context.

ex_btc8821a2ant_bt_info_notify()
btcoexist->btc_set_bt_reg()
halbtc_set_bt_reg()
rtl_c2h_content_parsing() is in turn called from:
rtl_c2hcmd_wq_callback()
rtl_c2hcmd_launcher()
which is preemptible context and from:
_rtl_pci_rx_interrupt
rtl_c2hcmd_enqueue()
which is obviously not preemptible but limited to C2H_BT_MP commands
which does invoke rtl_c2h_content_parsing().
Aside of that it can be reached from:
halbtc_get()

halbtc_get_bt_coex_supported_feature()

is_any_client_connect_to_ap() is using in_interrupt() to determine whether
it should acquire the lock prior accessing the list.
The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.
The function is called from:
- halbtc_get()
- halbtc_get()
halbtc_get_wifi_link_status()
- halbtc_display_dbg_msg()
halbtc_display_wifi_status()
halbtc_get_wifi_link_status()
All top level callers are part of the btc_coexist callback inferface and
are never invoked from a context which can hold the lock already.
The contexts which hold the lock are either protecting list add/del
operations or list walks which never call into any of the btc_coexist
interfaces.
In fact the conditional is outright dangerous because if this function
would be invoked from a BH disabled context the check would avoid taking
the lock while on another CPU the list could be manipulated under the lock.
Remove the in_interrupt() check and always acquire the lock.
To simplify the code further use list_empty() instead of walking the list
and counting the entries just to check the count for > 0 at the end.

Originally driver checks if firmware has left lps via reading the setting
of REG_TCR register. But this way may fail when firmware is frequently
changing power state. Therefore, firmware provides a safer option for
driver. When firmware leaves lps successfully, it sends a C2H response
to inform driver.

Some functions need the support of firmware with special version.

In current flow, driver issues power requests to firmware for entering or
leaving deep power mode. But driver does not wait for an ack from firmware
via reading CPWM register when driver requests to enter deep power mode.
The behavior will lead to unsynchronized state between firmware and driver.
Furthermore, consecutive same power requests may confuse firmware and leads
to unexpected value of CPWM register. This patch ensures that the power
request will wait for an ack from firmware and only send one power request
each time.

BT firmware will report BLE-HID and BLE-RCU in different profile.
We can distinguish the two profile from BT info now.
Add the coexistence for BLE-HID coexistence,
it can make BLE HID work more smoothly.
BLE-HID need to Tx/Rx packet more frequently to respond
user operation, but RCU doesn't.
In the case of RCU coexistence, it will make Wi-Fi have a
higher priority to earn more Wi-Fi throughput.
If BLE-HID go for the same case,
it will make user feel mouse is lagging.

During realtek USB wireless NIC initialization, it's unexpected
disconnection will cause urb sumbmit fail. On the one hand,
_rtl_usb_cleanup_rx will be called to clean up rx stuff, especially for
rtl_wq. On the other hand, disconnection will cause rtl_usb_disconnect
and _rtl_usb_cleanup_rx to be called. So, rtl_wq will be flush/destroy
twice, which will cause non-canonical address 0xdead000000000122 access
and general protection fault.
Fixed this issue by remove _rtl_usb_cleanup_rx when urb sumbmit fail.

Third set of patches for v5.10. Lots of iwlwifi patches this time, but
also few patches ath11k and of course smaller changes to other
drivers.
Major changes:
rtw88
* properly recover from firmware crashes on 8822c
* dump firmware crash log
iwlwifi
* protected Target Wake Time (TWT) implementation
* support disabling 5.8GHz channels via ACPI
* support VHT extended NSS capability
* enable Target Wake Time (TWT) by default
ath11k
* improvements to QCA6390 PCI support to make it more usable
