drm/rockchip: Fix YUV buffers color rendering
Currently, YUV hardware overlays are converted to RGB using
a color space conversion different than BT.601.
The result is that colors of e.g. NV12 buffers don't match
colors of YUV hardware overlays.
In order to fix this, enable YUV2YUV and set appropriate coefficients
for formats such as NV12 to be displayed correctly.
This commit was tested using modetest, gstreamer and chromeos (hardware
accelerated video playback). Before the commit, tests rendering
with NV12 format resulted in colors not displayed correctly.
Test examples (Tested on RK3399 and RK3288 boards
connected to HDMI monitor):
$ modetest 39@32:1920x1080@NV12
$ gst-launch-1.0 videotestrc ! video/x-raw,format=NV12 ! kmssink
