Fix ULPI reset polarity which caused a hard hang on Colibri T20 upon attempting to start the USB subsystem: This fixes my late commitd5a24d8b53(colibri_t20: fix usb operation and controller order) inadvertently having overwritten Stephen's previous commit2f6a7e8ce5(ARM: tegra: fix USB ULPI PHY reset signal inversion confusion). While at it also fix comment about on-module USB port. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
