[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.

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. |
