[Why]
DP compliance test case 400.3.2.3 is failed because in link loss interrupt
the current link settings is not used in the DP link training.
[How]
In link loss interrupt, use the current link settings in the following DP
link training.

[why & how]
For some specific eDP panel, we'd check the PSR-SU cap during boot
by reading the vendor specific DPCD, otherwise it will cause to
false report the eDP panel which supports PSR-SU as an non-PSR-SU
panel.
- add the vendor specific DPCD address in ddc_service_types header
- if specific eDP panel detected, check vendor specific DPCD for
PSR-SU cap

Clean up the sequence by making sure clk_mgr always builds a
reasonable clock table regardless of what we read from smu
by moving all defaults from resource soc struct to clk_mgr.
Now the only thing resource soc update does is read
the clock table and apply any DC specific policy decisions
to how clocks are populated in dml soc.

MEC firmware sometimes sends signal interrupts without a valid context ID
on end of pipe events that don't intend to signal any HSA signals.
This triggers the slow path in kfd_signal_event_interrupt that scans the
entire event page for signaled events. Detect these signals in the top
half interrupt handler to stop processing them as early as possible.
Because we now always treat event ID 0 as invalid, reserve that ID during
process initialization.

plane_state->uapi.crtc is not what we want to be looking at.
If bigjoiner is used hw.crtc is what tells us what crtc the plane
is supposedly using.
Not an actual problem on current hardware as the only FBC capable
pipe (A) can't be a bigjoiner slave and thus uapi.crtc==hw.crtc
always here. But when we get more FBC instances this will become
actually important.

Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.
The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.
Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.

Replace the DP-helper module with a display-helper module. The
support for DisplayPort becomes an internal option that drivers
have to select. Update all related Kconfig and Makefile rules.
Besides the existing code for DisplayPort, the new module will
contain helpers for other video-output standards, such as HDMI.
Drivers will have to select their required video-output helpers.
Linking all display-related code into a single module avoids the
proliferation of small kernel modules.
The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz,
and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace
to drm_display_helper.
v2:
* mention module parameters in commit message (Javier)
* distiguish between display module and DP support in Kconfig
* update Makefile rules for DP helpers
* move Kconfig rules into separate file under display/

The buffer objects created by cotables were missing fence reservations.
They are created from vmw_validation_res_validate which makes them miss
the ttm_eu_reserve_buffers which is called from vmw_validation_bo_reserve.
Cotables are the only resources which create a buffer object in the
create callback so make sure the code also reserves the slots.

The adev->pm.mutx is already held at the beginning of
amdgpu_dpm_compute_clocks/amdgpu_dpm_enable_uvd/amdgpu_dpm_enable_vce.
But on their calling path, amdgpu_display_bandwidth_update will be
called and thus its sub functions amdgpu_dpm_get_sclk/mclk. They
will then try to acquire the same adev->pm.mutex and deadlock will
occur.
By placing amdgpu_display_bandwidth_update outside of adev->pm.mutex
protection(considering logically they do not need such protection) and
restructuring the call flow accordingly, we can eliminate the deadlock
issue. This comes with no real logics change.
