Matt Redfearn 0d2808f338 MIPS: smp-cps: Add support for CPU hotplug of MIPSr6 processors ...

Introduce support for hotplug of Virtual Processors in MIPSr6 systems.
The method is simpler than the VPE parallel from the now-deprecated MT
ASE, it can now simply write the VP_STOP register with the mask of VPs
to halt, and use the VP_RUNNING register to determine when the VP has
halted.
