drm/mediatek: mtk_dpi: Use switch in mtk_dpi_config_color_format()

Browse Source 
In preparation for adding support for an additional color format,
convert the format conditional in mtk_dpi_config_color_format()
to a switch.
This also makes the concept of RGB being the default color format
a little more human readable.

This commit brings no functional differences.
