Now, that the Component Register mappings are stored, use them to enable and map the HDM decoder capabilities. The Component Registers do not need to be probed again for this, remove probing code. The HDM capability applies to Endpoints, USPs and VH Host Bridges. The Endpoint's component register mappings are located in the cxlds and else in the port's structure. Duplicate the cxlds->reg_map in port->reg_map for endpoint ports.
