KVM: arm64: Include VM type when checking VM capabilities in pKVM

Certain features and capabilities are restricted in protected mode. Most
of these features are restricted only for protected VMs, but some
are restricted for ALL VMs in protected mode.

Extend the pKVM capability check to pass the VM (kvm), and use that when
determining supported features.
