Subject: [PATCH v4 00/11] drm/bridge: dw-hdmi: implement bus-format negotiation and YUV420 support

This patchset is based on Boris's v10 "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 sincd v3 at [6]:
- Added "Plug atomic state hooks to the default implementation" on drm/bridge: dw-hdmi
- Also added these atomic state hooks in meson-dw-hdmi in patch 7
- Rebased on latest drm-misc-next including patches 1-7 of [1]

Changes since RFC v2 at [5]:
- Added fixes from Jonas, who tested and integrated it for Rockchip SoCs
- Added support for 10/12/16bit tmds clock calculation
- Added support for max_bcp connector property
- Adapted to Boris's v4 patchset
- Fixed typos reported by boris

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