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.

+ <para>These four pixel formats are raw sRGB / Bayer formats with
+16 bits per colour. Each colour component is stored in a 16-bit word.
