cpu/x86/lapic: Move LAPIC configuration to MP init

Implementation for setup_lapic() did two things -- call
enable_lapic() and virtual_wire_mode_init().

In PARALLEL_MP case enable_lapic() was redundant as it
was already executed prior to initialize_cpu() call.
For the !PARALLEL_MP case enable_lapic() is added to
AP CPUs.
