Series drm: Add component_match_add_of and convert users of drm_of_component_match_add | expand

Commit Message

Sean Anderson Dec. 22, 2022, 11:37 p.m. UTC 
Every user of this function either uses component_compare_of or
something equivalent. Most of them immediately put the device node as
well. Convert these users to component_match_add_of and remove
drm_of_component_match_add.
