[PATCH 24/36] drm/i915: Note that horizontal panning seems fine with 5k modes on skl+

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

I wasn't able to make horizontal panning misbehave on a KBL when
driving a 5120x2880 mode. So unless there is some hard to hit corner
case it seems we're fine on that front.
