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.

Clean up evbarm interrupt support a little:
...
* Define an ARM_INTR_IMPL option, which specifies a header file
describing the interrupt implementation for the platform. Use
this instead of the list of EVBARM_BOARDTYPE checks.
* Make the s3c2xx0 interrupt dispatch code a bit more generic, and move
it to a generic location so that other platforms can use it.
This eliminates all uses of the EVBARM_BOARDTYPE stuff, so delete it.
