This adds temporary entropy driver simulation for
nRF54l09 device since final entropy source is not
available yet.

TODO: Remove this commit when proper solution will be available.

@aescolar haven't you finished an implementation for a real one?

The upstream driver is for 54L05/10/15 so far.
L09 has a different CRACEN version.
For NCS we have the nrf_security diver, but I presume @e-rk wants to enable this one because the nrf_security driver also does not support an L09 device yet.

Yes, we need some entropy source, because many applications won't build without it.
