use generic DMA mapping code in powerpc V4

[Christian Zigotzky]

Next step: e15cd8173ef85e9cc3e2a9c7cc2982f5c1355615 (powerpc/dma: fix an 
off-by-one in dma_capable)

git checkout e15cd8173ef85e9cc3e2a9c7cc2982f5c1355615

The PASEMI onboard ethernet also works with this commit and the X5000 
boots without any problems.
