x86/mm/numa: Move early mptable evaluation into common code

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.
