Subject: Changes to support serialization with PCI devices

dev/ide_ctrl.cc:
    Properly serialize/unserialize the PciDev base class to get it to remap
    the MMU
dev/ns_gige.cc:
dev/ns_gige.hh:
    Remove the "addr" paramter from the constructor and change the device
    to use PCI based MMU mappings only
dev/pciconfigall.cc:
    Change comments
dev/pcidev.cc:
    Properly setup the MMU after a serialize
