[media] v4l2: add new pixel formats supported on dm365
add new macro V4L2_PIX_FMT_SGRBG10ALAW8 and associated formats to represent Bayer format frames compressed by A-LAW algorithm, add V4L2_PIX_FMT_UV8 to represent storage of CbCr data (UV interleaved) only.

28 <para>The following four pixel formats are raw sRGB / Bayer
29 formats with 10 bits per color compressed to 8 bits each,
30 using the A-LAW algorithm. Each color component consumes 8
31 bits of memory. In other respects this format is similar to
