Introduce support for bringing up Virtual Processors in MIPSr6 systems as CPUs, much like their VPE parallel from the now-deprecated MT ASE. The existing mips_cps_boot_vpes function fits the MIPSr6 architecture pretty well - it can now simply write the mask of running VPs to the VC_RUN register, rather than looping through each & starting or stopping as appropriate as is done for VPEs from the MT ASE. Thus the VP support is in general an extension & simplification of the existing MT ASE VPE (aka SMVP) support.
