powerpc/85xx: add HOTPLUG_CPU support
Add support to disable and re-enable individual cores at runtime on
MPC85xx/QorIQ SMP machines. Currently support e500v1/e500v2 core.
MPC85xx machines use ePAPR spin-table in boot page for CPU kick-off. This
patch uses the boot page from bootloader to boot core at runtime. It
supports 32-bit and 36-bit physical address.
