[PATCH] dt-bindings: gpio: add common consumer GPIO lines

[Krzysztof Kozlowski]

Typical GPIO lines like enable, powerdown, reset or wakeup are not
documented as common, which leads to new variations of these (e.g.
pwdn-gpios).  Add a common schema which serves also as a documentation
for preferred naming.
