ARM: shmobile: Add shared SCU CPU Hotplug code
Add CPU Hotplug functions for SCU equipped mach-shmobile SoCs.
The functions shmobile_smp_scu_cpu_die() together with
shmobile_smp_scu_cpu_kill() perform basic shutdown and
allows checking of shutdown status. These are written
to work together with SMP boot code in headsmp-scu.S.
