drm/amd/display: Prune Invalid Modes For HDMI Output
[Why]
1. HDMI does not have 6 bpc support. Having 6 bpc pass validation
does not comply with spec.
2. Validate 420 only for native HDMI, but not apply to pcon use
case.
3. Current mode validation log is not readable.
[how]
1. Cap 8 bpc for dp-hdmi converter.
2. Validate yuv420 for pcon use case as well,
if rgb/yuv444 8bpc cannot fit into pcon bw limitation of
the link from the converter to HDMI sink.
3. Add readable pixel_format and color_depth into debug log.
