usb: phy: tegra: switch to using devm_gpiod_get()

I would like to stop exporting OF-specific devm_gpiod_get_from_of_node()
so that gpiolib can be cleaned a bit, so let's switch to the generic
device property API.

I believe that the only reason the driver, instead of the standard
devm_gpiod_get(), used devm_gpiod_get_from_of_node() is because it
wanted to set up a pretty consumer name for the GPIO, and we now have
a special API for that.
