[PATCH v2] 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 already in use.

v2:
 - The error in the hog pattern was from my own bad addition, so fix the 
   patch to add gpio hog nodes.
