AirPrime module is resetting in loop

If the AirPrime module (WMP1XX, Q26XX, SL6087) is resetting in loop, the GPIO which ones are multiplexed with the keypad/COL should not be connected to ground, because the internal COL are pulled up to VCC_1V8, as the /RESET signal is also linked to VCC_1V8, so this can increase the power consumption on the VCC_1V8 at startup, and generate the system to perform reset in loop.
