YM2612 output updates, Add some Mega drive variations (#6150)
* 2612intf.cpp : Fix output bits, Device-fied YMF276, Add notes fm2612.cpp : Add output bit variation fmtowns.cpp : Add YMF276 placeholder for later model use this megadriv.cpp : Add config for when YM3438 is integreated in ASIC, Add handheld variations, Fix PAL sound clock * megadriv.cpp : Fix clock
