mfd: fusb302: Add EXTCON_USB_VBUS_EN for fusb302
Some rk3399 board(rk3399 MID or rk3399 VR) is use rk81x generated vbus.
So need fusb302 send a extcon to notify rk818 when OTG or DP cable plugin.
If use EXTCON_USB_HOST, the extcon will notify dwc3 and rk818_charger at
the same time,so need to add a new extcon EXTCON_USB_VBUS_EN.
