[PATCH 6/6] twl4030-usb: Don't report EVENT_ID when there is VBUS.

Some USB chargers tie the ID pin low via various resistors. So they can cause VBUS to be high and ID to be low. The 'A' end of an OTG cable never receives VBUS, it only ever generates it. So if we see VBUS and are not generating it, this must be a charger, not the A end of an OTG cable, so in tha
