colibri_t20: fix ulpi reset polarity 

Fix ULPI reset polarity which caused a hard hang on Colibri T20 upon
attempting to start the USB subsystem:

This fixes my late commit d5a24d8b53
(colibri_t20: fix usb operation and controller order) inadvertently
having overwritten Stephen's previous commit
2f6a7e8ce5 (ARM: tegra: fix USB ULPI PHY
reset signal inversion confusion).

While at it also fix comment about on-module USB port.
