soc: mediatek: add mtk-mmsys config API for mt8195 vdosys1

Add four mmsys config APIs. The config APIs are used for config
mmsys reg. Some mmsys regs need to be set according to the
HW engine binding to the mmsys simultaneously.

1. mtk_mmsys_merge_async_config: config merge async width/height.
   async is used for cross-clock domain synchronization.
2. mtk_mmsys_hdr_confing: config hdr backend async width/height.
3. mtk_mmsys_mixer_in_config and mtk_mmsys_mixer_in_config:
   config mixer related settings.
