hw/arm/stellaris: Implement watchdog timer
Implement the watchdog timer for the stellaris boards.
This device is a close variant of the CMSDK APB watchdog
device, so we can model it by subclassing that device and
tweaking the behaviour of some of its registers.

[PMM: rewrote commit message, fixed a few checkpatch nits,
added comment giving the URL of the spec for the Stellaris
variant of the watchdog device]
