KVM: arm64: Allow RES1 bits to be inferred from configuration

Browse source

So far, when a bit field is tied to an unsupported feature, we set
it as RES0. This is almost correct, but there are a few exceptions
where the bits become RES1.

Add a AS_RES1 qualifier that instruct the RESx computing code to
simply do that.
