KVM: arm64: Simplify handling of full register invalid constraint

Browse source

Now that we embed the RESx bits in the register description, it becomes
easier to deal with registers that are simply not valid, as their
existence is not satisfied by the configuration (SCTLR2_ELx without
FEAT_SCTLR2, for example). Such registers essentially become RES0 for
any bit that wasn't already advertised as RESx.
