NRF52: GPIOTE Static 400 µA

To all Nordic team,

Is there a patch in the pipe to fix GPIOTE used in the same time as I2C interface?

cf nordic bug:

http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.Rev2.errata%2Fdita%2Ferrata%2FnRF52832%2FRev2%2Flatest%2Fanomaly_832_89.html&cp=2_1_1_0_1_26

The pbm is that a lot of sensors are using I2C & interrupts(so GPIOTE) in the same time (ex: lsm6dsl, lis3mdl, hts221, lis2dh...) and NRF52 consumes 400uA statically.

Currently, nothing is done to desactivate I2C in the NRF52 but maybe someone has a PR coming soon.

Waiting your feedback.....
