Merge tag 'arm/soc/for-4.4/rpi-drivers' of https://github.com/Broadcom/stblinux into...

This pull request contains the Raspberry Pi firmware driver, for communicating
with the VPU which has exclusive control of some of the peripherals.

Eric adds the actual firmware driver and Alexander fixes the header file which
was missing include guards.
