ARM: tegra: usb_phy: Tracking circuit power down

1. Bring PD_TX out of power-down mode by writing
UHSIC_PADS_CFG1 register to 0.
2. Bring tracking circuit out of power-down mode by
clearing bit PD_TRK.
3. Add 25usec delay. This allows calibration complete.
4. Power down tracking circuit by setting PD_TRK=1.
