Timing Test Update

Hey Urs and Simon,

Important: I updated the phase scan to use the i2c addresses instead of the enabled ROC list.

Less Important: I also changed the mkConfig script so the basee on TBM Core B is always 00. This is because basee on TBM Core B, "Bits for Temperature measurement control", is an entirely different register than Core A. The change at this point is purely cosmetic, but the mkconfig script at some point will need these two values to be completely decoupled.

Unimportant: I also changed how the levels are set in the level scan... but I am still having a slight issue with the DTB.
