Implement the BUSDMA_IOMMU_XLATE method for the pcib and shub devices:
o   The pcib device selects between 32-bit or 64-bit direct mapped
    addresses. For 32-bit this means that the address is limited to
    2G.
o   The shub device limits the addresses to be offsets within an address
    space and then transposes the range to lie within the cacheable
    memory space.

In combination this guarantees that DMA memory will be allocated from
memory local to the device and lie within the 2G translation window
for 32-bit direct mapped DMA.
