Fuad Tabba afb91f5f8a KVM: arm64: Ensure that SME controls are disabled in protected mode 
KVM (and pKVM) do not support SME guests. Therefore KVM ensures
that the host's SME state is flushed and that SME controls for
enabling access to ZA storage and for streaming are disabled.

pKVM needs to protect against a buggy/malicious host. Ensure that
it wouldn't run a guest when protected mode is enabled should any
of the SME controls be enabled.
