Merge ^/head r363583 through r363738.

Move the bcm2835 firmware driver earlier in the boot.

It will be needed by other eaarly drivers.

While here make the dependency of the mailbox formal with MODULE_DEPEND.

Revert r363639 so I can use a more correct commit message

Have the bcm2835 firmware driver depend on the mailbox driver

The firmware driver uses the mailbox driver to communicate with the
firmware. Make this a more formal dependency.

Add a driver to talk to the Raspberry Pi firmware

Communicating with the Raspberry Pi firmware is currently handled by each
driver calling into the mbox driver, however the device tree is structured
such that they should be calling into a firmware driver.

Add a driver for this node with an interface to communicate to the firmware
via the mbox interface.

There is a sysctl to get the firmware revision. This is a unix date so can
be parsed with:

root@generic:~ # date -j -f '%s' sysctl -n dev.bcm2835_firmware.0.revision
