extcon: max77693: Set default uart/usb path by using platform data
This patch determine default uart/usb path by using platform data. The MAX77693 MUIC device can possibliy set USB/UART/AUDIO/USB_AUX /UART_AUX to internal h/w path of MUIC device. So, drvier should determine default uart/usb path. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Myungjoo Ham <myungjoo.ham@samsung.com>
