arm64: KVM: Make unexpected reads from WO registers inject an undef
Reads from write-only system registers are generally confined to
EL1 and not propagated to EL2 (that's what the architecture
mantates). In order to be sure that we have a sane behaviour
even in the unlikely event that we have a broken system, we still
handle it in KVM.
In that case, let's inject an undef into the guest.
Let's also remove write_to_read_only which isn't used anywhere.
