[PATCH 2/6] staging: bcm2835-firmware-gpio: Add needed mailbox defines to driver

[Michael Zoran]

The original change this driver is based on adds the needed mailbox
defines to include/soc/bcm2835/raspberrypi-firmware.h. That is not
appropriate at this time, so add the defines directly into the
driver source.

This change is based on:
https://github.com/raspberrypi/linux

Branch: rpi-4.11.y(commit efad03c3c86642dafccc03fcdd3ab84dd11e2ab7)
