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

Browse Source 
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.
