AMD northbridges: factor out CPU allocation
Factor CPU allocation out of AMD northbridge codes. As CPU topology
information is required for generation of certain ACPI tables, make
this code globally available.
For AMDK8 and AMDFAM10 northbridge, there is a possible case of
BSP CPU with lapicid!=0. We do not want to leave the lapic 0 from
devicetree unused, so always use that node for BSP CPU.
