When CONFIG_ARM_PMU is disabled, we get the following build error:

arch/arm64/kvm/sys_regs.c: In function 'pmu_counter_idx_valid':
arch/arm64/kvm/sys_regs.c:564:27: error: 'ARMV8_PMU_CYCLE_IDX' undeclared (first use in this function)
  if (idx >= val && idx != ARMV8_PMU_CYCLE_IDX)
                           ^
arch/arm64/kvm/sys_regs.c:564:27: note: each undeclared identifier is reported only once for each function it appears in

    idx = ARMV8_PMU_CYCLE_IDX;
          ^
arch/arm64/kvm/sys_regs.c: In function 'access_pmu_evtyper':
arch/arm64/kvm/sys_regs.c:638:14: error: 'ARMV8_PMU_CYCLE_IDX' undeclared (first use in this function)
   if (idx == ARMV8_PMU_CYCLE_IDX)
              ^

  write_sysreg(ARMV8_PMU_USERENR_MASK, pmuserenr_el0);

This patch fixes the build with CONFIG_ARM_PMU disabled.
