Subject: more modifications for cross-endian support. linux now gets to
 pciconfig

dev/alpha_console.cc:
    rather than acessing a byte array for alpha access, access the members
    **this requires an updated console**
dev/pcidev.cc:
    correctly type all the pci data and store in in little endian no
    matter what system we are on
dev/tsunami_uart.cc:
    correct a bug with the data type.
kern/linux/linux_system.cc:
    system type in hwprb needs to be endian happy as well.
