The responsibility for establishing HDM Decoder Capability based operation is more closely tied to port enabling than memdev enabling which is concerned with port enumeration. This later enables reusing @cxlhdm for probing / controlling "global enable" for the HDM Decoder Capability. For now, just do the nominal move.
