[v5,2/3] media: uapi: Add MEDIA_BUS_FMT_RGB888_3X8 media bus format

  This patch adds MEDIA_BUS_FMT_RGB888_3X8, used for the GiantPlus
GPM940B0 24-bit TFT panel, where the RGB components are transferred
sequentially on a 8-bit bus.

Notes:
    v2: New patch
    
    v3: No change
    
    v4: Add only MEDIA_BUS_FMT_RGB888_3X8, as we don't have to care about
        endianness
    
    v5: Also update Documentation/media/uapi/v4l/subdev-formats.rst
