usb: xhci: tegra: Power-off power-domains on removal
Currently the XUSB power domains used by the Tegra xHCI controller are never powered off on the removal of the driver, however, they will be powered off on probe failure. Update the removal code to be consistent with the probe failure path to power off the XUSB power domains.
