sb/intel/ibexpeak: Implement USB current settings

This is based on the sandybridge settings.
The current lookup table comes from the x201 vendor lookup table.

Tested: USB mouse and webcam still work and current registers are the
same as before. USB IR are not but the code follows EDS instead of the
register replay.
