[WATCHDOG] iTCO_wdt : correct status clearing
The iTCO_wdt code was not clearing the correct bits. It now clears the timeout status bit and then the SECOND_TO_STS bit and then the BOOT_STS bit. Note: we should first clear the SECOND_TO_STS bit before clearing the BOOT_STS bit. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
