drm/i915/psr: Compute Panel Replay/Adaptive Sync coexistence behavior

Browse source

Currently we are checking Panel Replay capability DPCD register in
intel_alpm.c and writing PR_ALPM_CTL_ALLOW_LINK_OFF_BETWEEN_AS_SDP_AND_SU
and PR_ALPM_CTL_AS_SDP_TRANSMISSION_IN_ACTIVE_DISABLE in PR_ALPM_CTL
register base on the informaion. Instead of directly accessing
intel_dp->pr_dpcd compute the behavior during psr_compute_config and store
it in intel_crtc_state.

v2:
  - inline added helpers
  - use intel_dp_attached_dp instead of passing as a parameter
