Hook in the per-CPU boot and sleep code in the shared
mach-shmobile SCU code. CPUs may be kept in the asm
routine until ->boot_secondary() when the per-CPU
boot vector is installed. At the end of ->die() the
asm sleep routine is invoked.

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.

Add SMP boot functions for SCU equipped mach-shmobile SoCs.
At this point shmobile_smp_scu_prepare_cpus() controls the SCU and
installs boot fn and arg, while shmobile_smp_scu_boot_secondary()
currently does nothing. In the future the boot function and arg
install code will be reworked, so the empty function is ground
work for that.
