Subject: [PATCH v6 11/27] cxl/port: Remove Component Register base address from struct cxl_dport

From: Robert Richter <rrichter@....com>

The Component Register base address @component_reg_phys is no longer
used after the rework of the Component Register setup which now uses
struct member @comp_map instead. Remove the base address.
