drm/vc4: Add support for gamma ramps. We could possibly save a bit of power by not requesting gamma conversion when the ramp happens to be 1:1, but at least if all the CRTCs are off the SRAM will be disabled. This should fix brightness sliders in a lot of fullscreen games. Signed-off-by: Eric Anholt <eric@anholt.net>
