[v9,06/15] cxl/port: Remove Component Register base address from struct cxl_port

Commit Message

From: Robert Richter <[e-mail]>

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.
