Add the separated files for media encoder on haswell

There exist a lot of changes about the media encoder between Haswell
and IvyBridge. For example: the VME programming and the corresponding
general media command. To be simple, the separated files are added for
Haswell. Otherwise it has to consider the complex backward compatibility.
