Revert "target/arm: Make number of counters in PMCR follow the CPU"
This reverts commit f7fb73b8cdd3f77e26f9fcff8cf24ff1b58d200f.
This change turned out to be a bit half-baked, and doesn't
work with KVM, which fails with the error:
"qemu-system-aarch64: Failed to retrieve host CPU features"
because KVM does not allow accessing of the PMCR_EL0 value in
the scratch "query CPU ID registers" VM unless we have first
set the KVM_ARM_VCPU_PMU_V3 feature on the VM.
Revert the change for 6.0.
