[patch 18/53] x86/mm/numa: Move early mptable evaluation into common code

[Thomas Gleixner]

There is no reason to have the early mptable evaluation conditionally
invoked only from the AMD numa topology code.

Make it explicit and invoke it from setup_arch() right after the
corresponding ACPI init call. Remove the pointless wrapper and invoke
x86_init::mpparse::early_parse_smp_config() directly.
