pciintel: Support alternate method to access PCI configuration space

On UltraSPARC IIi-based machines, the PCI configuration space is mapped
directly in the portion of the PBM (PCI Bus Interface Module) address
space. It is therefore not accessed indirectly via the config address
and config data registers but directly by accessing the respective
portion of the PBM address space.
