Jayachandran C. cd4c8d64ff MIPS XLP platform code update.
* Update the hardware access register definitions and functions to bring
  them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
  PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
  which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support
  >32 cpus.
