KVM: arm64: Return NOT_SUPPORTED to guest for unknown PSCI version
A subsequent change to KVM will allow negative returns from SMCCC
handlers to exit to userspace. Make way for this change by explicitly
returning SMCCC_RET_NOT_SUPPORTED to the guest if the VM is configured
to use an unknown PSCI version. Add a WARN since this is undoubtedly a
KVM bug.
