[PATCH 12/18] drm/i915: Reorganize intel_rotation_info

ville.syrjala

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

Throw out a bunch of unnecessary stuff from struct intel_rotation_info,
and pull most of the remaining stuff to live under an array of
per-color plane sub-structures.

What still remains outside the sub-structure will be reorgranized later
as well, but that requires more work elsewhere so leave it be for now.
