The Xilinx Video Framebuffer DMA IP supports video memory formats
that are not represented in the current V4L2 fourcc library. This
patch adds those missing fourcc codes. This includes both new
8-bit and 10-bit pixel formats.

These pixel formats should be documented in Documentation/media/uapi/v4l/.

If you read the convention, X:Y:Z is used to illustrate the sub-
sampling. The three previous are representing the number of bits, so
should have a comment like:
XVUY-8-8-8-8
AVUY-8-8-8-8
VUY-8-8-8
