[RFC/RFT usb-next v1 1/6] usb: mtu3: remove custom USB PHY handling

[Martin Blumenstingl <martin.blumenstingl-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org>]

The new PHY wrapper is now wired up in the core HCD code. This means
that PHYs are now controlled (initialized, enabled, disabled, exited)
without requiring any host-driver specific code.
Remove the custom USB PHY handling from the mtu3 driver as the core HCD
code now handles this.
