cxl/pci: Store component register base in cxlds
In preparation for defining a cxl_port object to represent the decoder
resources of a memory expander capture the component register base
address.
The port driver uses the component register base to enumerate the HDM
Decoder Capability structure. Unlike other cxl_port objects the endpoint
port decodes from upstream SPA to downstream DPA rather than upstream
port to downstream port.
