powerpc: Fix DMA offset for non-coherent DMA
After Becky's work we can almost have different DMA offsets between on-chip devices and PCI. Almost because there's a problem with the non-coherent DMA code that basically ignores the programmed offset to use the global one for everything. This fixes it.
