drm/ast: Add Atomic gamma lut support for aspeed
The current ast driver only supports legacy gamma interface.
This also fixes a Gnome3/Wayland error which incorrectly adds
gamma to atomic commit:
"Page flip discarded: CRTC property (GAMMA_LUT) not found"
I only tested remotely, so I wasn't able to check that it had
an effect on the VGA output. But when activating "Night Light"
in Gnome, ast_crtc_load_lut() is called.
v2: use the same functions as mgag200.
handle 16bits color mode.
v3: Check gamma_lut size in atomic check.
v4: revert 16bits mode, v1 was correct.
make sure gamma table are set when primary plane format
changes.
remove rgb888 format that is not used.
