Bluetooth: controller: Use NRF RNG entropy device

Browse source 
Use the NRF RNG entropy device as the entropy device for bt_rand and
controller internal functions when LLL is Nordic.
Using an entropy source with a significant increase in stack usage
will invalidate all stack size configurations in the system and lead
to stack overflow issues.
