device_prep_dma_cyclic may be call in audio trigger function which is
atomic context, so we make it atomic too.

 - change channel0 lock to spinlock.
 - Use polling to wait for channel0 finish running.

Hi Vinod,

Since Mark wouldn't like to have sound tree pulled into arm-soc to help
a couple of patches in the series get merged in the coming window, I can
not take the series as a whole to go with arm-soc.  It makes less sense
to have this patch go arm-soc then, so please take the patch.
