ok. will be replaced with "sdma_ick". I don't have 2420 for testing. I
tested it on 2430. My understanding is that, DMA clock interface is same
for 2420 and 2430. Correct me if am wrong.

This will be replaced with "sdma_fck"

I don't have setup to test this. I will do the changes and test it on
2430SDP which has similar change.
