Add an AR5416 PCU DMA stop method, as a check for the AR9130 is needed.

The reference driver has a 3ms delay for the AR9130 but I'm not as yet
sure why.  From what I can gather, it's likely waiting for some FIFO
flush to occur.

At some point in the future it may be worthwhile adding a WMAC
FIFO flush here, but that'd require some side-call through to the SoC
DDR flush routines.
