I agree with Peter that all DMA stopping related workarounds should be
in omap_stop_dma. I'd expect that DMA is stopped when returning
from there. Commit 9da65a9 was dealing with similar issue so probably
this looping should be implemented somewhere around those lines reading
& clearing the _CCR_EN bit?
