[media] v4l: Add 16-bit raw bayer pixel formats 



The formats added by this patch are:

	V4L2_PIX_FMT_SBGGR16
	V4L2_PIX_FMT_SGBRG16
	V4L2_PIX_FMT_SGRBG16

V4L2_PIX_FMT_SRGGB16 already existed before the patch. Rework the
documentation to match that of the other sample depths.

Also align the description of V4L2_PIX_FMT_SRGGB16 to match with other
similar formats.

16-bit Bayer formats





Description

===========



This format is similar to

:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`, except each pixel

has a depth of 16 bits. The least significant byte is stored at lower

memory addresses (little-endian).

These four pixel formats are raw sRGB / Bayer formats with 16 bits per

sample. Each sample is stored in a 16-bit word. Each n-pixel row contains

n/2 green samples and n/2 blue or red samples, with alternating red and blue

rows. Bytes are stored in memory in little endian order. They are

conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is

an example of one of these formats:



**Byte Order.**

Each cell is one byte.
