Improve the libmix parser efficiency by using short format

BZ: 146002

On baytrail, the GEN hardware support AVC short format parsing.
In multiple slice situation, the parsing work is a bottleneck for
CPU. If we use AVC short format, some slice header parsing work
can be done with GEN HW. This will increase the overall decoding
