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.

Fixes: 1cc8546474 ("drm/i915/psr: Use SU granularity information available in intel_connector")
Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/7284
