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 adjustments to support hdmi. Based on next-20221104 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I haven't updated the vdosys/mmsys/ethdr and mutex patches in a while in that test branch, they might be outdated..
