x86/cpu/AMD: Evaluate smp_num_siblings early
commit 1e1d7e25fd759eddf96d8ab39d0a90a1979b2d8c upstream
To support force disabling of SMT it's required to know the number of
thread siblings early. amd_get_topology() cannot be called before the APIC
driver is selected, so split out the part which initializes
smp_num_siblings and invoke it from amd_early_init().
[dwmw2: Backport to 4.9]
