That made me wonder if we should further divide the HVC space to have a
'pKVM only' range in addition to the privileged/unprivileged split, so
we could WARN in the core HVC handler in the pretty unlikely event that
we take a pKVM-only call in {n,h}VHE.

But yes there is no point in littering the code with is_protected_kvm_enabled()
checks all over, so:
