x86: introduce max_physical_apicid for bigsmp switching
a multi-socket test-system with 3 or 4 ioapics, when 4 dualcore cpus or
2 quadcore cpus installed, needs to switch to bigsmp or physflat.
CPU apic id is [4,11] instead of [0,7], and we need to check max apic
id instead of cpu numbers.
also add check for 32 bit when acpi is not compiled in or acpi=off.
