x86, acpi: Add MAX_LOCAL_APIC for 32bit
We should use MAX_LOCAL_APIC for max apic ids and MAX_APICS as number of local apics. Also apic_version[] array should use MAX_LOCAL_APICs. Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <4D0AD464.2020408@kernel.org> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
