Zheng Yang da59743ca6 drm/rockchip: hdmi: support modify color format

This patch is based on https://patchwork.kernel.org/patch/9801533,
add the drm property "hdmi_output_format", the possible value
could be:
     - RGB
     - YCBCR 444
     - YCBCR 422

To handle various subsampling of YCBCR output types, this property
allows two special automatic cases:
     - DRM_HDMI_OUTPUT_YCBCR_HQ
       This indicates preferred output should be YCBCR output,
       with highest subsampling rate by the source/sink, which
       can be typically:
	- ycbcr444
	- ycbcr422
	- ycbcr420
     - DRM_HDMI_OUTPUT_YCBCR_LQ
       This indicates preferred output should be YCBCR output, with
       lowest subsampling rate supported by source/sink, which can be:
	- ycbcr420
	- ycbcr422
	- ycbcr444

Default value of the property is set to 0 = RGB, so no changes if you
don't set the property.
