x86/apic: Build the x86 topology enumeration functions on UP APIC builds too

These functions are mostly pointless on UP, but nevertheless the
64-bit UP APIC build already depends on the existence of
topology_apply_cmdline_limits_early(), which caused a build bug,
resolve it by making them available under CONFIG_X86_LOCAL_APIC,
as their prototypes already are.
