cxl/port: Move endpoint HDM Decoder Capability init to port driver
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.
