video: sunxi_display: Convert to DM_VIDEO

Browse source 
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)

Say Y here to add support for using a cfb console on the HDMI, LCD
or VGA output found on most sunxi devices. See doc/README.video for
info on how to select the video output and mode.
Say Y here to add support for using a graphical console on the HDMI,

a simple_framebuffer device for Linux.
