[PATCH] ACPI: fix missing include for UP

[PATCH] ACPI: fix missing include for UP

apic.h does not get included on UP compiles.  That way the
APICTIMER_STOPS_ON_C3 is not there and UP boxen have no support for timer
broadcasting.  This was never noticed, because the lapic timer is only used
for profiling on UP.
