[PATCH 04/26] drm/dp: Add DPCD for configuring AS SDP for PR + VRR

[Ankit Nautiyal <ankit.k.nautiyal@intel.com>]

Add additional DPCDs required to be configured to support VRR with Panel
Replay. These DPCDs are specifically required for configuring Adaptive Sync
SDP and are introduced in DP v2.1.

v2:
 - Correct the shift for the bits. (Ville)
 - Add DP_PR_ prefix for the PR-related fields.
v3:
 - Use macro values in their shifted form to match the convention. (Ville)
v4:
 - Add macro for the mask. (Ville)
