The Renesas Camera Receiver Unit in the RZ/V2H SoC can output RAW
data captured from an image sensor without conversion to an RGB/YUV
format. In that case the data are packed into 64-bit blocks, with a
variable amount of padding in the most significant bits depending on
the bitdepth of the data. Add new V4L2 pixel format codes for the new
formats, along with documentation to describe them.

Changes in v3:

	- Switched from bayer-order specific formats to generic RAWnn

Changes in v2:

	- Added labels to the new formats in the documentation file
	- Added 20-bit formats

+These pixel formats are some of the Bayer RAW outputs for the Camera Receiver
+Unit in the Renesas RZ/V2H SoC. They are raw sRGB / Bayer formats which pack
+pixels contiguously into 64-bit units, with the 4 or 8 most significant
