  We're getting a reference RPi's firmware node in order to be able to
  communicate with it's driver. We should decrease the reference count on
  the dt node after being done with it.

  Pi3 and Compute Module 3 have a GPIO expander that the
  VPU communicates with.
  There is a mailbox service that now allows control of this
  expander, so add a kernel driver that can make use of it.
