Update driver code and board files to use new GPIO configuration flags such as GPIO_ACTIVE_LOW. Also add implementation of new port_* driver API as well as gpio_pin_interrupt_configure function. Tested on nrf52840_pca10056 board. Signed-off-by: Piotr Mienkowski <piotr.mienkowski@gmail.com> Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>
