[patch 29/46] ACPI: fix missing include for UP

[Thomas Gleixner <tglx@linutronix.de>]

From: Thomas Gleixner <tglx@linutronix.de>

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.
