Some final changes

[PastorL69]

• The algorithm is too heavy for Capcom HD. So it's now disabled. Doesn't really matter anyways.
• clkdiv was incorrectly set. It's now defined together with the dmdreader initialization function.
• Because clkdiv was incorrectly set, some timing based dmdreader pios have been adjust (/reverted incase of DE/Sega)
• x16 v2 is now based on 125MHz, instead of whatever it was before...

Every system is now confirmed working and stable.
