Subject: Re: [PATCH] usb: dwc3: don't reset device side if dwc3 was configured as host-only

It seems that this patch causes driver failed to initialize on rockchip rk3399 devices
when DWC3 controller is configured as dual role.

[    2.827119] dwc3 fe900000.usb: error -ETIMEDOUT: failed to initialize core
[    2.827881] dwc3: probe of fe900000.usb failed with error -110

After some tests I am preliminarily certain that this patch caused the failure.
