MLK-11340-42 usb: chipidea: usb vbus glitch check logic change This patch changes the vbus glitch check to cover usb otg certification case, so the possible cases of vbus rise: - USB vbus can reach AVV(4.4v), valid vbus. - USB vbus keeps above BSV(0.8v) but lower than AVV(4.4v) for more than 300ms, we think it's valid vbus event, this can meet usb otg certificataion case(B device can do connection in 1s when vbus is 4.0v). - USB vbus cannot be kept above BSV(0.8v) for more than 300ms, it's a vbus glitch. In case of vbus drop: if the vbus on flag is not set, it's a vbus glitch, otherwise it's a valid vbus drop event.
