video: sunxi_display: Convert to DM_VIDEO
DM_VIDEO migration deadline is already expired, but around
80 Allwinner boards are still using video in a legacy way:
===================== WARNING ======================
This board does not use CONFIG_DM_VIDEO Please update
the board to use CONFIG_DM_VIDEO before the v2019.07 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/migration.rst for more info.
====================================================
Convert the legacy video driver over to the DM_VIDEO framework. This is
a minimal conversion: it doesn't use the DT for finding its resources,
nor does it use DM clocks or DM devices for the outputs (LCD, HDMI, CVBS).
Tested in Bananapi M1+ Plus 1920x1200 HDMI out. (Jagan)
