drm/i915/display: Introduce dp/psr_compute_config_late()

Browse source

Introduce intel_dp_compute_config_late() to handle late-stage
configuration checks for DP/eDP features. For now, it paves path for
psr_compute_config_late() to handle psr parameters that need to be
computed late.

Move the handling of psr_flag for Wa_18037818876 and setting of non-psr
pipes to intel_psr_compute_config_late() as these are the last things
to be configured for PSR features.

v2: Update dp_compute_config_late() to return int.
