Since GICv4.1, it has become legal for an implementation to advertise GICR_{INVLPIR,INVALLR,SYNCR} while having an ITS, allowing for a more efficient invalidation scheme (no guest command queue contention when multiple CPUs are generating invalidations). Provide the invalidation registers as a primitive to their ITS counterpart. Note that we don't advertise them to the guest yet (the architecture allows an implementation to do this).
