usb: typec: hd3ss3220: Enable VBUS based on role state

Browse source

For systems where the ID pin isn't available as gpio use the ATTACHED_STATE
register instead to control vbus.

>From the datasheet:
"This is an additional method to communicate attach other
than the ID pin. These bits can be read by the application to
determine what was attached."

Use this method if id-gpios property is not set, but the connector node
has vbus-supply defined.
