Handle the 'nowayout' feature

-----------------------------

A few drivers use nowayout statically, i.e. there is no module parameter for it

and only CONFIG_WATCHDOG_NOWAYOUT determines if the feature is going to be

used. This needs to be converted by initializing the status variable of the

watchdog_device like this:

        .status = WATCHDOG_NOWAYOUT_INIT_STATUS,

Most drivers, however, also allow runtime configuration of nowayout, usually

by adding a module parameter. The conversion for this would be something like:

	watchdog_set_nowayout(&s3c2410_wdd, nowayout);

The module parameter itself needs to stay, everything else related to nowayout

can go, though. This will likely be some code in open(), close() or write().

Register the watchdog device

* WDOG_NO_WAY_OUT: this bit stores the nowayout setting for the watchdog.

  If this bit is set then the watchdog timer will not be able to stop.

  To set the WDOG_NO_WAY_OUT status bit (before registering your watchdog

  timer device) you can either:

  * set it statically in your watchdog_device struct with

	.status = WATCHDOG_NOWAYOUT_INIT_STATUS,

    (this will set the value the same as CONFIG_WATCHDOG_NOWAYOUT) or

  * use the following helper function:

  static inline void watchdog_set_nowayout(struct watchdog_device *wdd, int nowayout)

Note: The WatchDog Timer Driver Core supports the magic close feature and

the nowayout feature. To use the magic close feature you must set the

WDIOF_MAGICCLOSE bit in the options field of the watchdog's info structure.

	select WATCHDOG_CORE

	---help---

	This is the driver for the hardware watchdog timer on VIA

	southbridge chipset CX700, VX800/VX820 or VX855/VX875.

	To compile this driver as a module, choose M here; the module

	will be called via_wdt.

	Most people will say N.
