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 userspace 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).
