media: v4l: Add packed Bayer raw12 pixel formats
These formats are compressed 12-bit raw bayer formats with four different
pixel orders. They are similar to 10-bit variants. The formats added by
this patch are
V4L2_PIX_FMT_SBGGR12P
V4L2_PIX_FMT_SGBRG12P
V4L2_PIX_FMT_SGRBG12P
V4L2_PIX_FMT_SRGGB12P

Every two consecutive samples are packed into three +bytes. Each of the first two bytes contain the 8 high order bits of +the pixels, and the third byte contains the four least significants +bits of each pixel, in the same order. + +Each n-pixel row contains n/2 green samples and n/2 blue or red +samples, with alternating green-red and green-blue rows.
