ARM: smp_on_up: allow non-ARM SMP processors
Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs
supporting SMP must have the new CPU ID format, so check for this first.
Then check for ARM11MPCore, which fails the MPIDR check. Lastly check
the MPIDR reports multiprocessing extensions and that the CPU is part of
a multiprocessing system.
