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".
