[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.

	    <para>The following four pixel formats are raw sRGB / Bayer

	    formats with 10 bits per color compressed to 8 bits each,

	    using the A-LAW algorithm. Each color component consumes 8

	    bits of memory. In other respects this format is similar to
