Current adoption on top of nrfx only reads the GPIO->IN register. In order to read back an output state, nrf_gpio_pin_out_read has to be called. This patch concatinate the two read functions such that, if either IN or OUT register has a value 1 it will return this, else 0. Updating lib/nrfx submodule to latest version of master to get the new GPIO API to read pin direction. (nrfx: d37b16f2b894b0928395f6f56ca741287a31a244)
