From: Manjunath Hadli <manjunath.ha...@ti.com>
add new enum entries for supporting the media-bus formats on dm365.
These include some bayer and some non-bayer formats.
V4L2_MBUS_FMT_YDYUYDYV8_1X16 and V4L2_MBUS_FMT_UV8_1X8 are used
internal to the hardware by the resizer.
V4L2_MBUS_FMT_SBGGR10_ALAW8_1X8 represents the bayer ALAW format
that is supported by dm365 hardware.
