sound: soc: msm: set the .copy function realtime(disabled by default)

This is a hack,and doesn't fix totally the buffer underrun issues.
The code was taken from arch/arm/mach-msm/qdsp5/audio_out.c

arch/arm/mach-msm/qdsp5/audio_out.c's audio_write is very similar to
the alsa driver's alsa_send_buffer function.but had a difference:
It used code to set the write realtime,which I imported.
