cxl/port: Limit the port driver to just the HDM Decoder Capability

Browse source

Update the port driver to use cxl_map_component_registers() so that the
component register block can be shared between the cxl_pci driver and
the cxl_port driver. I.e. stop the port driver from reserving the entire
component register block for itself via request_region() when it only
needs the HDM Decoder Capability subset.
