Subject: [PATCH 02/13] ARM: dts: broadcom: bcm2835-rpi: Move non simple-bus
 nodes to root level

The 'gpu' and 'firmware' nodes are not MMIO devices, so they should not be
under a 'simple-bus'. Additionally, the "raspberrypi,bcm2835-power" node
is part of the firmware, so move it under the /firmware node.
