Most of code originally by James Cleverdon.
More stuff reformed in the mpparse sections - this time not apic stuff,
so we create mach_mpparse.h and stick it in there.
Abstracts out:
mpc_oem_bus_info() - stores mappings between buses and nodes/quads.
mpc_oem_pci_bus() - stores mappings between global and local pci bus numbers
Changes summit_check() into mps_oem_check() to generalise it.
