Change the Nimble stacksize from 16384 to 2048, the nimble application
starts as it should.
Haven't had time to look into it anymore, it should've been 16k for a
reason.
We´ll have to trim stacksizes to leave some ram for the actual application
though.
I guess the board should start advertising some data, which it doesn't.
I´m not familiar with Mynewt/Nimble at all, our BLE products use the zephyr
rtos/stack together with MCUboot.
This is tested on nrf52832-dk.
