cxl: Change sslbis handler to only handle single dport

While cxl_switch_parse_cdat() is harmless to be run multiple times, it is
not efficient in the current scheme where one dport is being updated at
a time by the memdev probe path. Change the input parameter to the
specific dport being updated to pick up the SSLBIS information for just
that dport.
