dev/tsunami_uart.cc:
dev/tsunami_uart.hh:
Cleaned up includes and changed device from FunctionalMemory to
PioDevice for detailed boot
dev/ns_gige.cc:
The ethernet dev uses two BARs, and the first bars size was being set
incorrectly.
dev/tsunamireg.h:
I don't know why we were using the superpage as the PCI memory addr.
Changed and works correctly with detailed boot.
