PATCH v2 1/1 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.
