Also update Documentation/watchdog/watchdog-kernel-api.txt to introduce: (1)the new elements in the watchdog_device and watchdog_ops struct; (2)the new API "watchdog_init_timeouts".
Reasons: (1)kernel already has two watchdog drivers are using "pretimeout": drivers/char/ipmi/ipmi_watchdog.c drivers/watchdog/kempld_wdt.c(but the definition is different) (2)some other dirvers are going to use this: ARM SBSA Generic Watchdog

Should this function also enforce "t < wdd->timeout", and should watchdog_timeout_invalid() enforce "t > wdd->pretimeout" ?
