Subject: extcon: palmas: Fix boot up state of VBUS when using GPIO detection

From: Roger Quadros <[email protected]>

commit 62e6d1e59c77316768a663d1328390b4cd33801f upstream.

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.
