powerpc/85xx: add cpu hotplug support for e500mc/e5500
Add support to disable and re-enable individual cores at runtime.
This supports e500mc/e5500 core based SoCs.
To prevent the register access race, only read/write RCPM registers
in platform_cpu_die() on the boot cpu instead of accessing by individual
cpus. Platform implementations can override the platform_cpu_die().
