Fix one bug that host can't work after insmod gadget module
at dual-role mode, the root cause of this issue is the usbcmd.rs
is cleared by chipidea udc code.
usb: chipidea: udc: don't touch DP when controller is in host mode
When the controller is configured to be dual role and it's in host mode,
if bind udc and gadgt driver, those gadget operations will do gadget
disconnect and finally pull down DP line, which will break host function.
