media: platform: msm: Add demux support for mediabox

Browse source 
Add audio stream buffer interface to write the Audio demux data
to audio decoder buffers. Add support in TSIF driver to append
LPASS subsystem time stamps to Transport Stream packets in TSIF HW.
This is required for AV sync & clock recovery handling
for mediabox project based on LE platform.
