Modified Files:
        src/sys/arch/alpha/include: pci_machdep.h
        src/sys/arch/alpha/pci: tsc.c tsp_dma.c tsreg.h tsvar.h

Log Message:
The Tsunami / Typhoon chipsets have a static "monster window" for DMA
that allows for up to 32GB of RAM to be direct-mapped if the PCI device
can issue a 64-bit address (the monster window lives at 0x10000000000).
Enable this window and provide this to the PCI bus as a "dmat64".
