[media] v4l2: add new pixel formats supported on dm365

Browse Source 
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.

<title>Description</title>
<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
