drm/udl: Convert to drm_atomic_helper_dirtyfb()

Browse Source 
The infrastruture for atomic modesetting allows us to use the generic
code for dirty-FB and damage handling. Switch over udl and remove the
driver's implementation. The simple-pipe's update function now picks up
the primary plane's damage and updates a minimal region of the screen.
