After startup ublox-sara-r4 code sets the MDM_POWER signal to input using a deprecated configuration macro. This was the only use of the modem context API to configure a pin. Refactor the API to not take the flags as an input but instead select between the flags to be used when the pin is active and a disconnected state. Use this API instead of a separate direct configure call when initializing the modem pins. Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>
