sunxi: musb: Stop treating not having a vbus-det gpio as an error
On some boards the otg is wired up in host-only mode in this case we
have no vbus-det gpio.
Stop logging an error from sunxi_usb_phy_vbus_detect() in this case, and
stop treating sunxi_usb_phy_vbus_detect() returning a negative errno, as
if a charger is plugged into the otg port.
