			12-bit packed Bayer formats


			Description
			===========

			These four pixel formats are packed raw sRGB / Bayer formats with 12
			bits per colour. Every two consecutive samples are packed into three
			bytes. Each of the first two bytes contain the 8 high order bits of
			the pixels, and the third byte contains the four least significants
			bits of each pixel, in the same order.

			Each n-pixel row contains n/2 green samples and n/2 blue or red
			samples, with alternating green-red and green-blue rows. They are
			conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
			Below is an example of a small V4L2_PIX_FMT_SBGGR12P image:

			Byte Order.
			Each cell is one byte.
