tegra_usb_phy_close() is supposed to undo the effects of
tegra_usb_phy_init(). It is also currently added as the USB PHY shutdown
callback, which is wrong, since tegra_usb_phy_init() is only called
during probing wheras the shutdown callback can get called multiple
times. This then leads to warnings about unbalanced regulator_disable if
the EHCI driver is unbound and bound again at runtime.
