powerpc/kvm: Remove unused references for MMCR3/SIER2/SIER3 registers
Commit 57dc0eed73ca ("KVM: PPC: Book3S HV P9: Implement PMU save/restore in C") removed the PMU save/restore functions from assembly code and implemented these functions in C, for power9 and later platforms. After the code refactoring, Performance Monitoring Unit (PMU) registers became part of "p9_host_os_sprs" structure and now this structure is used to save/restore pmu host registers, for power9 and later platfroms. But we still have old unused registers references. Patch removes unused host_mmcr references for Monitor Mode Control Register 3 (MMCR3)/ Sampled Instruction Event Register 2 (SIER2)/ SIER3 registers from "struct kvmppc_host_state".
