Jouni Högander a99cac460d drm/i915/psr: Fix for Panel Replay X granularity DPCD register handling
DP specification is saying value 0xff 0xff in PANEL REPLAY SELECTIVE UPDATE
X GRANULARITY CAPABILITY registers (0xb2 and 0xb3) means full-line
granularity. Take this into account when handling Panel Replay X
granularity informed by the panel.
