gpio-usbdetect: Update charger type before notifying USB cable status 



USB controller driver expects to receive charger type before USB cable
connected or not notification. Without charger type nofication, USB
controller driver doesn't know what is connected on USB port which result
into no USB enumeration when USB cable is connected to SDP port. Hence
update charger type as SDP when USB cable is connected.
