Some devices pack or compress raw formats before storing them to memory.
They defined custom V4L2 fourcc codes that were specific to the
bayer-order.

Now that the kernel has support for generic RAW media bus codes, add
their counterpart V4L2 fourcc codes for the device-specific packing or
compression too.
