drm/i915: Optimize out redundant dbuf slice updates

Browse source

if the new dbuf slices are a superset of the old
dbuf slices then we don't have to do anything in
intel_dbuf_post_plane_update(). Restructure the code
to skip such redundant dbuf slice updates. The main
benefit is slightly less confusing logs.
