To prevent VBUS contention, the am335x MUSB phy senses VBUS first before transitioning to host mode. However, for host-only mode, VBUS could be directly tied to 5V power rail which could prevent MUSB transitions to host mode. This change receives dr_mode of the controller then bypass the first VBUS sensing for host-only mode, so that MUSB can work in host mode event if VBUS is tied to 5V.
