[RFC PATCH v5 09/11] media: uapi: define audio sample format fourcc type

The audio sample format definition is from alsa, the header file is include/uapi/sound/asound.h, but don't include this header file directly, because in user space, there is another copy in alsa-lib. There will be conflict in userspace for include videodev2.h & asound.h and asoundlib.h

Here still use the fourcc format.
