Subject: [PATCH 8/8] SFI: expose IO-APIC routines to SFI, not just ACPI

From: Feng Tang <feng.tang@...el.com>

change condition from
	#ifdef CONFIG_ACPI
to
	#if defined(CONFIG_ACPI) || defined(CONFIG_SFI)

for several io_apic related APIs which will be used by both
ACPI and SFI.

this change will ensure the success kernel build whe
CONFIG_SFI=y and CONFIG_ACPI=n
