[PATCH v3 11/13] cxl/port: Move endpoint HDM Decoder Capability init to port driver

[Dan Williams <dan.j.williams@intel.com>]

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.
