Edward A. James e4c98db335 watchdog: allow a device path to be specified
Currently systemd hardcodes the use of /dev/watchdog. This is a legacy
chardev that points to watchdog0 in the system.

Modify the watchdog API to allow a different device path to be passed
and stored. Opening the watchdog defaults to /dev/watchdog, maintaining
existing behavior.
