Add timing hacks for DDR X - DDR 2014. This will fix input delay.

[makoflagkk]

There is a lot of input delay in DDR X. No matter what offset I set it too it is either too early or too late. If you added timing hacks to change the individual offsets like Marvelous, perfect, great, good and bad it would help out a lot with the input delay. Please make this a feature if possible.
