drm: Add drm_rotation_90_or_270()

Browse source 
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.

v2: Drop the BIT()
    Convert all new intel_rotation_90_or_270() calls
    Deal with superfluous code shuffling
