Extend this callback to process CXL Protocol errors as well. Achieve by defining a new struct cxl_cper_rec_data to include cxl_cper_event_rec and other fields of CXL protocol errors which will be defined in future patches.

These CPER records obtained from GHES module, will rely on a registered callback to be notified to the CXL subsystem in order to be processed. Call the existing cxl_cper_callback to notify the CXL subsystem on a Protocol error. The defined trace events cxl_aer_uncorrectable_error and cxl_aer_correctable_error currently trace native CXL AER errors. Reuse them to trace FW-First Protocol Errors.
