Handle 64bit DMA addresses on PCI for platforms that can (currently only
...
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

Make sure that private DMA flags don't overlap with standard DMA flags;
...
start these at 0x10000 to leave room for an increase in the latter.
