vbus-supply is already in the 'connector' node, you don't need it here.

If not put here, 'regulator_get' only can follow the legacy way to get
vbus regulator.
Currently, there's no one to use the 'vbus-supply' property.
From my understanding, the 'vbus-supply' is the chip level property,
not connector type property.
