Simon Kågström bfdad565ae ARM: ixp4xx: Make dma_set_coherent_mask common, correct implementation
Non-PCI devices can use the entire 32-bit range, PCI dittos are
limited to the first 64MiB.

Also actually setup coherent_dma_mask.

The patch has been verified on a board with 128MiB memory, one
ipx4xx_eth device and a e100 PCI device.
