As Angelo suggested previously, this could be written slightly shorter as
* @edge_cfg_in_mmsys: Edge configuration for DPI output has to be set in MMSYS.

I know this isn't one of the formats supported by MT8186, but since we're using
platform-agnostic formats now... This else branch in theory could also run for a
format like MEDIA_BUS_FMT_YUYV8_1X16. Would it make sense to set
MTK_DPI_RGB888_SDR_CON in that case?
