Since commit 93390c0a1b20 ("arm64: KVM: Hide unsupported AArch64 CPU
features from guests") we can hide cpu features from guests. Apply
this to a long standing issue where guests see a PMU available, but
it's not, because it was not enabled by KVM's userspace.

Hi Christoffer,

I think this patch got into the PULL by mistake, because you pointed out
to me a while back that it broke migration.

Thanks for the reminder to go and try to fix it though!

Thanks,
drew
