This driver misses calling iounmap() in remove to undo the ioremap()
called in probe.
Add the missed call to fix it.

A Synopsys USB2.0 core used in Huawei Kunpeng920 SoC has a bug which
might cause the host controller not issuing ping.
Bug description:
After indicating an Interrupt on Async Advance, the software uses the
doorbell mechanism to delete the Next Link queue head of the last
executed queue head. At this time, the host controller still references
the removed queue head(the queue head is NULL). NULL reference causes
the host controller to lose the USB device.
Solution:
After deleting the Next Link queue head, when has_synopsys_hc_bug set
to 1，the software can write one of the valid queue head addresses to
the ASYNCLISTADDR register to allow the host controller to get
the valid queue head. in order to solve that problem, this patch set
the flag for Huawei Kunpeng920
There are detailed instructions and solutions in this patch:

During dwc2 driver probe, after gadget registration to the udc class
driver, if exist any builtin function driver it immediately bound to
dwc2 and after init host side (dwc2_hcd_init()) stucked in host mode.
Patch postpone gadget registration after host side initialization done.

If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ehci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.

The PMC needs to be notified separately about HPD (hotplug
detected) signal being high after mode entry. There is a bit
"HPD High" in the Alternate Mode Request that the driver
already sets, but that bit is only valid when the
DisplayPort Alternate Mode is directly entered from
disconnected state.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter
set*uid() syscalls according to its configured security policy. In
preparation for adding analagous support in the LSM for set*gid()
syscalls, we add the requisite hook here. Tested by putting print
statements in the security_task_fix_setgid hook and seeing them get hit
during kernel boot.

This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0.
This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.
The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.
Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.
There have been discussions how to fix that, but revert seems to be the
least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
