Add support for the BGR888_1X24 image formats.

No existing media bus codes describe exactly the way data is transferred
on the CSI-2 bus. This is not a new issue, the CSI-2 YUV422 8-bit format
is described by MEDIA_BUS_FMT_UYVY8_1X16 which is an arbitrary
convention and not an exact match. Use the MEDIA_BUS_FMT_BGR888_1X24 to
follow the same convention, based on the order in which bits are
transmitted over the CSI-2 bus.
