[WHY]
Need to fix some broken logic and sequencing in initial commit

[HOW]
Fix logic handling override deprogramming when exiting SQ128.

Don't exit early from dp_set_hw_lane_settings for DP2/FIXED_VS case.

Move LTTPR 128b/132b check out of  requires_hwss and check during
runtime, as LTTPR caps are not populated on initial call.

Add pending_test_pattern to link state to allow HWSS to set FFE overrides
on retimer TX and/or skip setting APU TX FFE depending on requested pattern.

Use updated clock source for SQ128 override sequence.

Skip HW FFE preset programming when performing test pattern overrides.

<title>drm/amd/display: Add DP audio BW validation</title>

<content type='text'>
[Why]
Timings with small HBlank (such as CVT RBv2) can result in insufficient
HBlank bandwidth for audio SDP transmission when DSC is active. This
will cause some higher bandwidth audio modes to fail.

The combination of CVT RBv2 timings + DSC can commonly be encountered
in MST scenarios.

[How]
Add DP audio bandwidth validation for 8b/10b MST and 128b/132b SST/MST
cases and filter out modes that cannot be supported with the current
timing config.

[why &amp; how]
we have two SSC_En:
we get ssc_info from dce_info for MPLL_SSC_EN.
we used to call VBIOS cmdtbl's smu_info's SS persentage for DPRECLK SS info,
is used for DP AUDIO and VBIOS' smu_info table was from systemIntegrationInfoTable.

since dcn35 VBIOS removed smu_info, driver need to use integrationInfotable directly.

<title>drm/amd/display: switch DC over to the new DRM logging macros</title>

<content type='text'>
For multi-GPU systems it is difficult to tell which GPU a particular
message is being printed for and that is undesirable because it
complicates debugging efforts. Also, the new macros allow us to enable
logging for particular parts of the codebase more selectively (since we
no longer need to throw everything at DRM_DEBUG_KMS()). So, for the
reasons outlined above we should switch to the new macros.

We can accomplish this by using the existing DC_LOGGER code to pass
around the relevant `struct drm_device` which will be fed to the new
macros in logger_types.h. Also, we must get rid of all instances of the
DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use
the DC logger there and we can simply refer to the macros directly
there instead.
