Subject: [PATCH 1/2] extcon: usb-gpio: Add level trigger support
Now extcon-usb-gpio only supports for GPIO egdge trigger, but VBUS/ID
gpios' detection can be triggered by the level trigger on some platforms.
Thus intoduce one property 'extcon-gpio,level-trigger' to identify this
situation.

Either one of id-gpio or vbus-gpio must be present. Both can be present as well.
- id-gpio: gpio for USB ID pin. See gpio binding.
- vbus-gpio: gpio for USB VBUS pin.
