Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Use devm_gpio_request_one() to make cleanup paths simpler.
Also, GPIOF_DIR_OUT | GPIOF_INIT_LOW is replaced with
GPIOF_OUT_INIT_LOW.

Since we changed the behaviour of the set_timeout operation in the
watchdog API, we need to change the allready converted drivers so
that they update the timeout field at the end of the set_timeout
operation.

Add two nowayout helpers for the Watchdog Timer Driver Kernel API.
And apply this to the already converted drivers.
Note: s3c2410_wdt lost the nowayout feature during the conversion.

Due to the whole single instance based watchdog API we use static data
for the wm831x watchdog which means that if the system tries to register
a second one we end up trying to register the same miscdevice again,
corrupting the miscdevice list. Work around this by checking for duplicate
registrations until we get a watchdog core.

The WM831x series of devices provide a watchdog with configurable
behaviour on timer expiry.
Currently this driver support refreshes via a register or GPIO line and
autonomous refreshes from a hardware source (eg, a clock).
