Fix dma_tc_handle() to call d40_desc_remove() and d40_desc_done() only
for non-cyclic transfers, as this was breaking ux500_pcm since
introduced in:

Hello Vinod,
the bug fixed by this patch was around for some time, but the affected
driver (ux500_pcm) will be enabled in next release cycle for other
reasons so this patch can safely go on -next.
Would you take it your tree?
Thanks,
Fabio
