Hello DRM Maintainers,

I would like to merge this patch via drm-intel/drm-intel-next. Is that
ok to you? This is adding define into drm_dp.h header for the only
value listed in eDP/DP spec on DP_PANEL_REPLAY_CAP_X_GRANULARITY
register. I'm using this define to fix a problem in our Panel Replay
granularity detection in our xe/i915 display driver.

BR,
Jouni Högander
