Subject: [PATCH RFC v2 0/8] drm/bridge: dw-hdmi: implement bus-format negotiation and YUV420 support

This patchset is based on Boris's v2 "drm: Add support for bus-format negotiation" at [1]
patchset to implement full bus-format negotiation for DW-HDMI, including YUV420 support and
10/12/16bit YUV444, YUV422 and RGB. The Color Space Converter support is already implemented.

And the counterpart implementation in the Amlogic Meson VPU dw-hdmi glue :
- basic bus-format negotiation to select YUV444 bus-format as DW-HDMI input
- YUV420 support when HDMI2.0 YUV420 modeset

This is a follow-up from the previous attempts :
- "drm/meson: Add support for HDMI2.0 YUV420 4k60" at [2]
- "drm/meson: Add support for HDMI2.0 4k60" at [3]

Changes since RFC v1 at [4]:
- Rewrote negociation using the v2 patchset, including full DW-HDMI fmt negociation
