Implement the machine restart hook using the SoC's watchdog timer module.
To support this, define a DT binding for the watchdog module, and add it
to the device tree.
The downstream rpi-split branch contains a full watchdog timer driver
implementation, which also implements the restart hook. However, the
restart function is largely separate from the watchdog driver, so for
simplicity, the restart hook is implemented here directly in the main
machine source file.
Overall structure (separate setup/restart) functions derived from the
picoxcell ARM support.
Watchdog register IO sequence taken from code by Simon Arlott. Note that
the watchdog module is not documented in BCM2835-ARM-Peripherals.pdf.

This branch contains a set of device-tree conversions for Marvell Orion
platforms that were staged early but took a few tries to get the branch
into a format where it was suitable for us to pick up.
Given that most people working on these platforms are hobbyists with
limited time, we were a bit more flexible with merging it even though
it came in late.
