[PATCH 7/7] DMAENGINE: add COH 901 318 AMBA/PrimeCell extension

[Linus Walleij]

This adds a dummy extenstion for handling PrimeCell configuration
on the COH 901 318. We might start to use the data passed in
soonish, since hard-coding the source/target addresses for DMA
into the DMA platform config is probably a bad idea.
