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.
