Change in coreboot[master]: nb/intel/x4x: Use a struct for dll settings instead of an array

[Arthur Heymans (Code Review)]

Hello Patrick Rudolph, Philippe Mathieu-Daudé, Paul Menzel, build bot (Jenkins),

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#3).

nb/intel/x4x: Use a struct for dll settings instead of an array

This makes the code more readable since it avoids messing with two
dimensional arrays and needing remember what the indices mean.

Also introduces an unused coarse element which is 0 for all default
DLL settings on DDR2.
