drm/mediatek: mtk_dpi: Add support for additional output formats

Browse Source 
Add support for configuring the Display Parallel Interface block
to output YUV444 8/10 bits, YUV422 10/12 bits (8 bits support is
already present), BGR 8-bits, and RGB 10-bits.

The enablement of the various additional output formats in SoCs
platform data will be done in a different change.
