Maxime Ripard d677c9052e drm/edid: Split deep color modes between RGB and YUV444
[ Upstream commit 4adc33f36d ]

The current code assumes that the RGB444 and YUV444 formats are the
same, but the HDMI 2.0 specification states that:

   The three DC_XXbit bits above only indicate support for RGB 4:4:4 at
   that pixel size. Support for YCBCR 4:4:4 in Deep Color modes is
   indicated with the DC_Y444 bit. If DC_Y444 is set, then YCBCR 4:4:4
   is supported for all modes indicated by the DC_XXbit flags.

So if we have YUV444 support and any DC_XXbit flag set but the DC_Y444
flag isn't, we'll assume that we support that deep colour mode for
YUV444 which breaks the specification.

In order to fix this, let's split the edid_hdmi_dc_modes field in struct
drm_display_info into two fields, one for RGB444 and one for YUV444.
