Wayne Chang b246caa680 phy: tegra: xusb: Explicitly configure HS_DISCON_LEVEL to 0x7
The USB2 Bias Pad Control register manages analog parameters for signal
detection. Previously, the HS_DISCON_LEVEL relied on hardware reset
values, which may lead to the detection failure.

Explicitly configure HS_DISCON_LEVEL to 0x7. This ensures the disconnect
threshold is sufficient to guarantee reliable detection.
