[PATCH] watchdog: kempld: use pretimeout member of watchdog_device struct

[Thomas Richard <thomas.richard@bootlin.com>]

Th driver was written whereas pretimeout wasn't supported by the watchdog
core. So the pretimeout was stored in the driver data.

Now the core has pretimeout support, so use it.
