Precedence: bulk

Add support for HDMI Tx on MT8195.

This includes a split of the current "legacy" hdmi driver into a common
library of functions and a two dedicated compilation units with specific
code for mt8167 and another for the "new" mt8195 SoC.

Support for the new mt8195 hdmi phy and the dpi/drm_drv adjustements to
support hdmi.

Based on next-20221014

test branch with dts and various "in flight" patches available here:
https://gitlab.com/granquet/linux/-/tree/granquet/linux-next_HDMI

I haven't updated the vdosys/mmsys/ethdr and mutex patches in a while
in that test branch, they might be outdated..

Changes in v2:
- Removed syscon requirement from the hdmi node
- Use as much as possible bit FIELD_PREP/FIELD_GET macros across all the
  patches
- Make cec optional dynamically instead of hardcoded with a flag
- Renamed hdmi variants to v1 (legacy) and v2 (mt8195) while waiting for
  a better name
- Rework hdmi v2 code to use a connector (same as v1)
- Remove "magic" 0x43 addr special handling in hdmi ddc code
- Link to v1: https://lore.kernel.org/r/20220919-v1-0-4844816c9808@baylibre.com
