Subject: [PATCH] Opening /dev/watchdog before /dev/watchdog0

Both nodes reach the first watchdog, but OpenIPC's sysupgrade looks
only for a process holding /dev/watchdog. A divinus holding
/dev/watchdog0 was not found, so the keeper was never armed and the
camera reset in the middle of the flash erase once divinus was gone.
