Modified Files:
        src/sys/arch/alpha/pci: tsp_dma.c tsvar.h

Log Message:
- Don't bother issuing a warning if we program the WBASE / WSM register
  to different values than the firmware.
- Reduce the differences in how we initialize the DMA tags vis a vis the
  other Alpha implementations.
- Use Window 2 to provide a 1G @ 3G PCI SGMAP window on systems with more
  than 1G of RAM, rather than falling back on the ISA DMA window which is
  small and could get starved by PCI devices.
- Make sure we set TBASE to 0 for direct-mapped windows.
