I have implemented the interrupt handle for IRQ 17 for receive error 
and underflow/overflow.  However, the devices are running for 2 days 
without channel swapped.  I will keep them running.

I will test it on EVM board as well.

We have tested the element mode for dma_op_mode.  It works fine, we 
don't see any channel swapping in this mode.
