usb: chipidea: introduce CI_HDRC_CONTROLLER_VBUS_EVENT glue layer use
Some vendors glue layer need to handle some events for vbus, eg,
some i.mx platforms (imx7d, imx8mm, imx8mn, etc) needs vbus event
to handle charger detection, its charger detection is finished at
glue layer code, but not at USB PHY driver.
