extcon: lt8711uxe2: fix usb role issue when usb cable disconnect

Currently usb role only can be set device mode and host mode,
if remove usb cable, usb role is still device mode, this is
incorrect.

Through connected state, host_mode and device_mode value to set
usb role, can help fix usb suspend issue.
