misc: mic: scif: scif_ports: Fix copy 'n' paste error

__scif_get_port() has never taken 'port' as an argument since
its inception back in 2015.  Probably document the proper arguments
expected 'start' and 'end'.

Fixes the following W=1 kernel build warnings:

 drivers/misc/mic/scif/scif_ports.c:36: warning: Function parameter or member 'start' not described in '__scif_get_port
 drivers/misc/mic/scif/scif_ports.c:36: warning: Function parameter or member 'end' not described in '__scif_get_port'
 drivers/misc/mic/scif/scif_ports.c:36: warning: Excess function parameter 'port' description in '__scif_get_port'
