Fix AY PSG clock divider function when exists, Update emulation core (MAME AY PSG and compatibles - includes noise routine updates)
Fix configuration flag, Add MSX Darky sound expander to preset
Clock divider isn't affected to expanded mode's tone and noise generator?
By doubling the internal clock frequency.
In expanded mode, the same tone period is an octave higher than in compat mode.
In expanded mode, the noise period is twice as fast as currently implemented.
