Minor mods to DMA interface - get rid of unnecessary args. Allow DMA functions to return status flags.
Note: Changing code to have DMA interface indicate when I/O is done (a la NetBSD) was considered. It was rejected due to questionable backward compatability
with ISA DMA and MAC obio DMA
Added irqack from NetBSD (though this feature should really be in the
PCI interrupt handlers)
