drm/mediatek: dpi: Add YUV422 output support
Dp_intf supports YUV422 as output format. In MT8195 Chrome project,
YUV422 output format is used for 4K resolution.
To support this, it is also needed to support color format transfer.
Color format transfer is a new feature for both dpi and dpintf of MT8195.
The input format could be RGB888 and output format for dp_intf should be
YUV422. Therefore, we add a mtk_dpi_matrix_sel() helper to update the
DPI_MATRIX_SET register depending on the color format.
