usb: dwc2: Fix some error handling paths
dwc2_driver_probe() calls dwc2_lowlevel_hw_init() which deassert some reset
lines.
Should an error happen in dwc2_lowlevel_hw_init() after calling
reset_control_deassert() or in the probe after calling
dwc2_lowlevel_hw_init(), the reset lines remain deasserted.
Add some devm_add_action_or_reset() calls to re-assert the lines if needed.
Update the remove function accordingly.
This change is compile-tested only.
