[PATCH v2] extcon: usb-gpio: Don't miss event during suspend/resume

[Roger Quadros]

Pin state might have changed during suspend/resume while
our interrupts were disabled and if device doesn't support wakeup.

Scan for change during resume for such case.

- only check for state change during resume if device wakeup is not supported
