Pull watchdog fixes from Wim Van Sebroeck:

   - the WDIOC_GETSTATUS return value
   - the unregister of all NMI events on exit
   - the loading of the iTCO_wdt driver after the conversion to the
     lpc_ich mfd model."

  watchdog: core: fix WDIOC_GETSTATUS return value
  watchdog: hpwdt: Unregister NMI events on exit.
