mdk: Add option to avoid replacing MDK peripheral addresses

In very rare cases, somebody wants to include the nrf.h for simulation
without replacing the hard real HW addresses from the MDK with the ones
for simulation. Add an option (macro) to enable this use case.
Note this option (NRF_H_NO_BSIM_REDEFS) should be used with great care.
