Samsung watchdog driver updates

[Wim Van Sebroeck]

Hi Ben,

I added them to the linux-2.6-watchdog tree so that they can be included
in this merge window.

I also created a fix for the removal of the driver (the misc_deregister
needs to happen first so that userspace access is removed before removing
the rest of the driver).
Can you test and give feedback?

Thanks,
Wim.

    watchdog: s3c2410_wdt - Fix removing of platform device
    
    When removing the watchdog platform device, we need to
    disable the access to userspace first. It makes no sense
    to remove the drivers clock, irq's, ... and then disable
    usersapce access.
    the order of removal has also been changed so that it
    is the reverse of probing (this way the clock is also
    disabled sooner).
