KVM: PPC: Book3S HV: Save/restore new PMU registers
Power ISA v3.1 has added new performance monitoring unit (PMU) special
purpose registers (SPRs). They are:
Monitor Mode Control Register 3 (MMCR3)
Sampled Instruction Event Register A (SIER2)
Sampled Instruction Event Register B (SIER3)
Add support to save/restore these new SPRs while entering/exiting
guest. Also include changes to support KVM_REG_PPC_MMCR3/SIER2/SIER3.
Add new SPRs to KVM API documentation.
