MIPS: PCI: use information from 1-wire PROM for IOC3 detection
IOC3 chips in SGI system are conntected to a bridge ASIC, which has a 1-wire prom attached with part number information. This changeset uses this information to create PCI subsystem information, which the MFD driver uses for further platform device setup.
