  1. drm: fix wrong degamma/shaper TFs on NV12 

    For BT.709, the AMD driver-specific color management properties define
the inverse OETF for plane degamma and blend predefined TFs and the OETF
for plane shaper and CRTC regamma TFs.

By correctly setting degamma and shaper TFs to NV12 planes, we can bring
degamma and shaper+3D LUT back and remove the workaround made in [1].
