Add NV15 and NV20 pixel formats used by the Rockchip Video Decoder for
10-bit buffers.

NV15 and NV20 is 10-bit 4:2:0/4:2:2 semi-planar YUV formats similar to
NV12 and NV16, using 10-bit components with no padding between each
component. Instead, a group of 4 luminance/chrominance samples are
stored over 5 bytes in little endian order:

YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes

The '15' and '20' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a
multiple of 8 for NV15 and 4 for NV20.
