MFC r273257:
Add a driver for the TI watchdog.
The TI watchdog timer is present on BeagleBone's. Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled. We need
to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog. This
is also a reflection of the watchdog(9) API.
In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.
