The TI Davinci DM644x and the TI Sierra AM335x both feature a
watchdog. Enable it on the AM335x as well. The next part is that
we can enable the watchdog for the shutdown. E.g. in case the
system does not reboot after the shutdown.
The shutdown is executed last and only after the shutdown target
has been reached. For time timeout we need to use the same interval
as the watchdog (as both drivers don't allow to change the timeout
interval).
Provide custom systemd config files to enable the watchdog handling. For
systemd we depend on the image containing and using systemd as init script.
In case we build images without systemd we will need to install the
old watchdog. Maybe it is time to create a MACHINE_FEATURE for watchdog.
