The sim presence pin allows the simtrace2 to inform the modem about the presence of the simcard. On a generic simcard slot a button is pressed by the simcard which generate a high or low voltage level. Even though there are specifications of minipcie or ngff defining this signal, certain modems behave different. Certain modems require different signals from the specification. Extend the usb protocol to set the behaviour at runtime. Related: SYS#6946 Change-Id: I77118114ba873fdf0778137402888b40f2442456
