The chipidea/udc.c file sends a CI_HDRC_CONTROLLER_RESET_EVENT to the wrapper drivers when it calls hw_device_reset(), but that function is not called from chipidea/host.c. The intent of this event is to allow the wrapper driver to do any wrapper specific things after the reset bit has been set in the usb command register. Therefore, add this event hook in the host role after we toggle that bit.
