Christophe JAILLET b6e30a54a5 usb: dwc2: Fix some error handling paths
[ Upstream commit ada050c691 ]

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.
