soc: mediatek: Add all settings to mtk_mmsys_ddp_dpi_fmt_config func
The difference between MT8186 and other ICs is that when modifying the
output format, we need to modify the mmsys_base+0x400 register to take
effect. So when setting the dpi output format, we need to call
mtk_mmsys_ddp_dpi_fmt_config to set it to MT8186 synchronously.
Commit a071e52f75d1 ("soc: mediatek: Add mmsys func to adapt to dpi
output for MT8186") lacked some of the possible output formats and also
had a wrong bitmask.
Add the missing output formats and fix the bitmask.
While at it, also update mtk_mmsys_ddp_dpi_fmt_config() to use generic
formats, so that it is slightly easier to extend for other platforms.
