fix the subarch build again after ACPI breakage

This patch:

[ACPI] check "maxcpus=N" early -- same as NR_CPUS check.
http://bugzilla.kernel.org/show_bug.cgi?id=2317

Broke by putting maxcpus (a variable which is only exported by mpparse.c) into parse_cmdline_early().

The fix is to make it depend on the correct CONFIG_ option.

In the subarchitectures:

CONFIG_X86_SMP is the one that means "I want standard x86 smp code" and that's what this should depend on.
