cpu/amd/fam10h-15h: Fix Family 15h boot hang when BSP lift enabled
The existing code did not allow for the second core of the BSP to
reside on an APIC ID other than 1, leading to a boot hang on Family
15h processors when APIC_ID_OFFSET was set to anything other than 0.
Furthermore, insufficient AP stack space was allocated for AP start.
