From: Stephen Warren <swarren at nvidia.com>
Ensure that the USB ULPI signals are not tri-stated, and have no pull-
up or pull-down.
Ensure that the pingroup hosting the USB ULPI reset signal (GPIO PV0 or
PV1 depending on the board, so UAC) is not tri-stated, and has no pull-
up or pull-down.
This change appears larger than it is due to the grouping and sorting of
the pin configuration data.
