[PATCH 1/2] dt-bindings: input: gpio-keys: add pinctrl states

[Kendall Willis]

Document pinctrl properties on the gpio-keys device node. By using the
wakeup pinctrl state, the pins are able to wakeup the system from a
low-power state. The default pinctrl state describes the default pin
configuration.
