Documentation: Explain DDR3 read training

Add lots of colorful graphics to explain DDR3 read training in detail,
what is done inside MCH and what needs to be done on firmware level.

Besides read training give a short explanation what DDR3 "FlyBy" is and
compare it with DDR2 DIMMs.

Besides the SVG all sources files are added.
