[Core/Sound] fixed PSG power-on latched register (verified on VA4 MD1 hardware)
...
Initial test that indicated power-on latched register was noise attenuation register was flawed because it wasn't done after a "cold" power-on. It appears the latched value is not totally reseted when doing a quick power off/on cycle (which was done with initial test) and would keep last value being set.
