[Intel-gfx] [PATCH 7/7] drm/i915: Use enum plane instaad of numbers

[ville.syrjala at linux.intel.com]

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

Change the update_plane() plane checks to use enum plane, and
also fix up the error message to say something that's not total
nonsense.

FIXME killing the checks entirely is probably a better idea
