[WHY]
Some DSC timing failed at bandwidth validation due to hactive
can't be evenly divided on each ODM segment.

[HOW]
Borrow from hblank to increase hactive to support these timing.

[WHY]
For better power profiling knowing the detile
buffer size at a given point in time
would be useful.

[HOW]
Add interface to retrieve detile buffer from
dc state.

This commit addresses a null pointer dereference issue in
hwss_setup_dpp(). The issue could occur when pipe_ctx->plane_state is
null. The fix adds a check to ensure `pipe_ctx->plane_state` is not null
before accessing. This prevents a null pointer dereference.

Early return possible if context has no clk_mgr.
This will lead to an invalid power profile being returned
which looks identical to a profile with the lowest power level.
Add back logic that populated the power profile and overwrite
the value if needed.

[Why]
The mechanism to backup and restore plane states doesn't maintain
refcount, which can cause issues if the refcount of the plane changes
in between backup and restore operations, such as memory leaks if the
refcount was supposed to go down, or double frees / invalid memory
accesses if the refcount was supposed to go up.

[How]
Cache and re-apply current refcount when restoring plane states.

[Why]
There are some pipe scaler validation failure when the pipe is phantom
and causes crash in DML validation. Since, scalar parameters are not
as important in phantom pipe and we require this plane to do successful
MCLK switches, the failure condition can be ignored.

[How]
Ignore scalar validation failure if the pipe validation is marked as
phantom pipe.

[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.

[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer

[Why]
1. HDMI does not have 6 bpc support. Having 6 bpc pass validation
does not comply with spec.
2. Validate 420 only for native HDMI, but not apply to pcon use
case.
3. Current mode validation log is not readable.

[how]
1. Cap 8 bpc for dp-hdmi converter.
2. Validate yuv420 for pcon use case as well,
   if rgb/yuv444 8bpc cannot fit into pcon bw limitation of
   the link from the converter to HDMI sink.
3. Add readable pixel_format and color_depth into debug log.

[Why]
Implement the new backlight_level_params structure as part of the VBAC
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]
Modified existing functions to include the new backlight_level_params
structure.

[Why/How]
Move the wait for pending updates past prepare_bandwidth if the previous
update was not a full update to reduce the average time it takes to
