AUX Pull Down Rework.

All Eaglemont cards (both Fab1 and Fab2) as delivered from the factory have 100 kΩ
pull-up resistors on AUXP and AUXN. These cards should be re-worked so that there
are 100 kΩ pull-downs on all AUXP and AUXN signals. There are only pull-downs on
AUX.
Eaglemont cards that are to be used for Display Port require this re-work. This is
independent of any other re-works required.
In the figure below, the resistors are incorrectly pulling up to 3.3V when they should
be pulling to GROUND.
Note: All rework should use lead-free solder in order to keep the board RoHS compliant.
