[ Upstream commit 4ea0bf2a52f1eea76578eac5a9148d95f5e181c0 ]
In commit "phy: tegra: xusb: Add usb-phy support", an OTG capable PHY
device, such as phy-usb2.0 device of Jetson-TX1 platform, will be
bound to the tegra-xusb-padctl driver by the following line in
tegra_xusb_setup_usb_role_switch().
port->usb_phy.dev->driver = port->padctl->dev->driver;
With this, dev_pm_ops set of tegra-xusb-padctl driver will be invoked
for the OTG capable PHY incorrectly as below logs show.
This commit fixes the issue by assigning an empty driver to it.
