drm/amd/display: remove redundant freesync parser for DP
When updating connector under drm_edid infrastructure, many calculations
and validations are already done and become redundant inside AMD driver.
Remove those driver-specific code in favor of the DRM common code.

[Why]
Initialize the new backlight_level_params structure as part of the ABC
framework, the information in this structure is needed to be passed down
to the DMCUB to identify the backlight control type, to adjust the
backlight of the panel and to perform any required conversions from PWM
to nits or vice versa.
[How]
Created initial framework of the backlight_level_params struct and
modified existing functions to include the new structure.

This is caused by lost memory during early init phase. First time driver
is removed, memory is freed but when second time the driver is inserted,
VBIOS dmub is not active, since the PSP policy is to retain the driver
loaded version on subsequent warm boots. Hence, communication with VBIOS
DMUB fails.
Fix this by aborting further communication with vbios dmub and release
the memory immediately.

drm/amd/display: Clear update flags after update has been applied
[Why]
Since the surface/stream update flags aren't cleared after applying
updates, those same updates may be applied again in a future call to
update surfaces/streams for surfaces/streams that aren't actually part
of that update (i.e. applying an update for one surface/stream can
trigger unintended programming on a different surface/stream).
For example, when an update results in a call to
program_front_end_for_ctx, that function may call program_pipe on all
pipes. If there are surface update flags that were never cleared on the
surface some pipe is attached to, then the same update will be
programmed again.
[How]
Clear the surface and stream update flags after applying the updates.

drm/amdgpu/gfx11: Apply Isolation Enforcement to GFX & Compute rings
This commit applies isolation enforcement to the GFX and Compute rings
in the gfx_v11_0 module.
The commit sets `amdgpu_gfx_enforce_isolation_ring_begin_use` and
`amdgpu_gfx_enforce_isolation_ring_end_use` as the functions to be
called when a ring begins and ends its use, respectively.
`amdgpu_gfx_enforce_isolation_ring_begin_use` is called when a ring
begins its use. This function cancels any scheduled
`enforce_isolation_work` and, if necessary, signals the Kernel Fusion
Driver (KFD) to stop the runqueue.
`amdgpu_gfx_enforce_isolation_ring_end_use` is called when a ring ends
its use. This function schedules `enforce_isolation_work` to be run
after a delay.
These functions are part of the Enforce Isolation Handler, which
enforces shader isolation on AMD GPUs to prevent data leakage between
different processes.

drm/amd/display: Configure DTBCLK_P with OPTC only for dcn401
[WHY]
DTBCLK_P is used to generate virtual pixel clock, and to drive the HPO
stream encoder clock. Programming the required clock when
enabling/disabling both components can cause issues.
For example, if HPO is being disabled and clock source is changed to
REFCLK, virtual pixel rate will then be wrong, causing issues in CRTC.
[HOW]
Only program the DTBCLK_P when programming CRTC, as its expected it will
be enabled prior to HPO, and disabled after HPO in all valid cases.

drm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'
An issue was identified in the dcn21_link_encoder_create function where
an out-of-bounds access could occur when the hpd_source index was used
to reference the link_enc_hpd_regs array. This array has a fixed size
and the index was not being checked against the array's bounds before
accessing it.
This fix adds a conditional check to ensure that the hpd_source index is
within the valid range of the link_enc_hpd_regs array. If the index is
out of bounds, the function now returns NULL to prevent undefined
behavior.

drm/amd/display: Clip rect size changes should be full updates
[Why]
In cases where an MPO plane is being dragged around partially off-screen,
it is possible to get a flip where the only scaling parameters to change
are the clip rect size and position. Currently, clip rect size changes
are considered medium updates, which can result in the clip rect being used
for HW programming being larger than the clip rect that was used for the
last DML validation. This can lead to mismatches in different parts of the
pipe and can result in a p-state hang.
[How]
- consider clip rect size changes scaling changes, therefore full updates
- refactor get_scaling_info_update_type for clarity
- remove clip_size_change update flag
Clip rect size changes were previously demoted from full updates as an
optimization when the MPO + ODM policy changed to always pre-allocate MPO
pipes, but it created the issue described above. Personally testing this
use case, the performance feels fine with full update spam, and we expect
this is a fairly infrequent use case. If the performance needs to be
optimized in the future, consider reworking the entire update type logic
to run a DML pass and determine the update type based on what DML says
will actually change.
