drm/amd/display: Add debugfs entry to force YUV420 output

Browse source

[Why]
Even if YUV420 is available for video mode, YUV444 is still
automatically selected. This poses a problem for compliance tests.

[How]
Add a per-connector debugfs entry "force_yuv420_output" to force
selection of YUV420 mode.
