usb: dwc2: set op_state to peripheral when resume ...
The operation mode of controller will change to peripheral when
resume if PD is power off during suspend, current code disconnect
hcd and set lx state to L3 in this case to make sure the controller
will be reinit in device mode, but that's not enough, the op_state
is still host which is change when init or ID change interrupt
occur. If the ID change happened after suspend the driver would
miss the interrupt, so when the application call the pullup function
to stop gadget and start again to change to another function, the
disconnect gadget operation can't be done and the gadget restart
directly. This will result in NULL point when gadget work. This
patch set op_state to OTG_STATE_B_PERIPHERAL when resume in this
case.
