Linux boots... various fixes to make console work correctly

dev/console.cc:
    commented out code that checks if an interrupt is happening before issuing one
    because they can get lost when linux boots
dev/console.hh:
    added a setPlatform function to set the platform to interrupt
dev/platform.hh:
dev/tsunami.cc:
dev/tsunami.hh:
    Added virtual functions to post console interrupts
dev/tsunami_io.cc:
    allowed a 64bit read of the PIC since we can't do a physical byte read
dev/tsunami_uart.cc:
    moved TsunamiUart to PioDevice
    various little fixes to make linux work
dev/tsunami_uart.hh:
    Made Tsunami_Uart a PIO device
dev/tsunamireg.h:
    added some UART defines and used the ULL macros
kern/linux/linux_system.cc:
    commented out waiting for gdb
