[PATCH 01/15] drm: Add drm_rotation_90_or_270()

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

We have intel_rotation_90_or_270() in i915 to check if the rotation is
90 or 270 degrees. Similar checks are elsewhere in drm, so let's move
the helper into a central place and use it everwhere.
