usb: typec: anx7411: use devm_pm_runtime_enable()
anx7411_i2c_probe() enables runtime PM before returning successfully, but
anx7411_i2c_remove() tears down the Type-C partner state, workqueue, dummy
I2C device, mux, switch and port without disabling runtime PM.
Use devm_pm_runtime_enable() so runtime PM is disabled automatically on
driver detach. Since devres action registration can fail, route that
failure through the existing probe unwind path.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.
