unified amdgpu device attribute node functions:
1. add some helper functions to create amdgpu device attribute node.
2. create device node according to device attr flags on different VF mode.
3. rename some functions name to adapt a new interface.
v2:
1. remove ATTR_STATE_DEAD, ATTR_STATE_ALIVE enum.
2. rename callback function perform to attr_update.
3. modify some variable names

the swsmu or powerplay(hwmgr) need to handle task according to different VF mode,
this function to help query vf mode.
vf mode:
1. SRIOV_VF_MODE_BARE_METAL: the driver work on host OS (PF)
2. SRIOV_VF_MODE_ONE_VF : the driver work on guest OS with one VF
3. SRIOV_VF_MODE_MULTI_VF : the driver work on guest OS with multi VF

When GPU got timeout, it would notify an interested part
of an opportunity to dump info before actual GPU reset.
A usermode app would open 'autodump' node under debugfs system
and poll() for readable/writable. When a GPU reset is due,
amdgpu would notify usermode app through wait_queue_head and give
it 10 minutes to dump info.
After usermode app has done its work, this 'autodump' node is closed.
On node closure, amdgpu gets to know the dump is done through
the completion that is triggered in release().
There is no write or read callback because necessary info can be
obtained through dmesg and umr. Messages back and forth between
usermode app and amdgpu are unnecessary.
v2: (1) changed 'registered' to 'app_listening'
(2) add a mutex in open() to prevent race condition
v3 (chk): grab the reset lock to avoid race in autodump_open,
rename debugfs file to amdgpu_autodump,
provide autodump_read as well,
style and code cleanups
v4: add 'bool app_listening' to differentiate situations, so that
the node can be reopened; also, there is no need to wait for
completion when no app is waiting for a dump.
v5: change 'bool app_listening' to 'enum amdgpu_autodump_state'
add 'app_state_mutex' for race conditions:
(1)Only 1 user can open this file node
(2)wait_dump() can only take effect after poll() executed.
(3)eliminated the race condition between release() and
wait_dump()
v6: removed 'enum amdgpu_autodump_state' and 'app_state_mutex'
removed state checking in amdgpu_debugfs_wait_dump
Improve on top of version 3 so that the node can be reopened.
v7: move reinit_completion into open() so that only one user
can open it.
v8: remove complete_all() from amdgpu_debugfs_wait_dump().

There is no need to use amdgpu_mm_wreg_mmio_rlc()
during initialization time because this interface
is only designed for debugfs case to access the
registers which are only permitted by RLCG during
run-time. Therefore, turn back rlcg write for gfx_v10.
If we not turn back it, it will raise amdgpu load failure.

According to drm_plane_create_zpos_property() function documentation,
all planes zpos range should be set if zpos property is supported.
However, the rcar-du driver didn't set primary plane zpos range. Since
the primary plane's zpos is fixed, set it immutably.

While the property is not mandatory for drivers to implement, mixing

The simple-bridge driver supports multiple simple or dumb bridges,
covered by different compatible strings but otherwise identical DT
bindings. Some of those bridges have undocumented bindings, while others
are documented in text form in separate files. Group them all in a
single binding and convert it to YAML.
The psave-gpios property of the adi,adv7123 is dropped, as it isn't
supported by the driver and isn't specified in any DT file upstream.
Support for power saving is available through the enable-gpios property
that should cover all the needs of the ADV7123 (as the device only has a
/PSAVE pin and no enable pin).

[Why]
We're sending the drm vblank event a frame too early in the case where
the pageflip happens close to VUPDATE and ends up blocking the signal.
The implementation in DM was previously correct *before* we started
sending vblank events from VSTARTUP unconditionally to handle cases
where HUBP was off, OTG was ON and userspace was still requesting some
DRM planes enabled. As part of that patch series we dropped VUPDATE
since it was deemed close enough to VSTARTUP, but there's a key
difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be
blocked if we're holding the pipe lock.
There was a fix recently to revert the unconditional behavior for the
DCN VSTARTUP vblank event since it was sending the pageflip event on
the wrong frame - once again, due to blocking VUPDATE and having the
address start scanning out two frames later.
The problem with this fix is it didn't update the logic that calls
drm_crtc_handle_vblank(), so the timestamps are totally bogus now.
[How]
Essentially reverts most of the original VSTARTUP series but retains
the behavior to send back events when active planes == 0.
Some refactoring/cleanup was done to not have duplicated code in both
the handlers.
Fixes: 16f17eda8bad ("drm/amd/display: Send vblank and user events at vsartup for DCN")
Fixes: 3a2ce8d66a4b ("drm/amd/display: Disable VUpdate interrupt for DCN hardware")
