[nrf noup] Disable mpsl before factory reset

We can speed up flash operations while performing a factory reset by disabling mpsl before that. Thanks to that flash operations do not wait for mpsl synchronization and all write operations take less time. Signed-off-by: Arkadiusz Balys <[email protected]>
