firmware: allow to change the sim presence pin polarity
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 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.
