cpu/amd/fam10h-fam15h: Correctly create APIC ID on single node systems 

The existing code generated an incorrect boot APIC ID from node and
core number for single node packages, leading to a boot failure when
the second node was installed.

Properly generate the boot APIC ID from node and core number.
