watchdog: allow setting deadline for opening /dev/watchdogN. This allow one to set a maximum time for which the kernel

up, or the board gets reset. This allows fallback logic in the

• bootloader to attempt some recovery (for example, if an automatic

  update is in progress, it could roll back to the previous version) commit, commit, [[https://git.kernel.org/linus/c2eac35bc2717abd585a3eede879d75461685bc7
