Subject: [PATCH] dt-bindings: raspberrypi,bcm2835-firmware: Add 'power' and gpio-hog nodes

Add missing child nodes for the RaspberryPi firmware. The firmware
implements a power domain provider in a 'power' node. GPIO hog nodes are
also supported, but the node name pattern was wrong and failed to match
them.
