drm/i915: Read DSC capabilities of the HDMI2.1 PCON encoder
This patch adds support to read and store the DSC capabilities of the
HDMI2.1 PCon encoder. It also adds a new field to store these caps,
The caps are read during dfp update and can later be used to get the
PPS parameters for PCON-HDMI2.1 sink pair. Which inturn will be used
to take a call to override the existing PPS-metadata, by either
writing the entire new PPS metadata, or by writing only the
PPS override parameters.
v2: Restructured the code to read all capability DPCDs at once and store
in an array in intel_dp structure.
v3: rebase
