[PATCH v2] drm: Remove some unused stuff from drm_plane

[ville.syrjala at linux.intel.com]

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

There's a bunch of unused members inside drm_plane, bloating the size of
the structure needlessly. Eliminate them.

v2: Remove all of it from kernel-doc too
