drm/amd/display: Fix primary EDP link detection
[HOW&WHY]
EDP link detection must
be updated to support a primary EDP with a
link index of greater than 0.
* SWDEV-342936 - dc: DSC bringup for SAG 1.5
[WHY]
SmartAccess Graphics 1.5 (a.k.a SmartMux 1.5)
requires seamless switching between GPUs
with DSC enabled.
[HOW]
Moved DSC programming to
apply_single_control_ctx_to_hw before the stream
enablement logic to ensure the CRC checker provides valid
values for non-black frames
allowing the system to come out of forced PSR on
d2i.
Added additional logic to both generate a black
frame through setVisibility calls and keep track
of the CRCs values for this black frame when
coming out of forced PSR.
Updating logic for DalRegKey_DisableDSC to disable
DSC on EDP and all ports for systems.
[CLEANED]
dc: Moved DSC programming to before stream enablement
[HOW&WHY]
Moved DSC programming to
apply_single_control_ctx_to_hw before the stream
enablement logic.
