extcon: palmas: Fix boot up state of VBUS when using GPIO detection
If USB cable is connected prior to boot, we don't get any interrupts so we must manually check the VBUS state and report it during probe. If we don't do it then USB controller will never know that peripheral cable was connected till the user unplugs and replugs the cable.
