watchdog: fix initialisation printout in s3c2410_wdt

watchdog: fix initialisation printout in s3c2410_wdt

Looks like a typo creeped in, and driver prints
s3c2410-wdt s3c2410-wdt: watchdog active, reset abled, irq abled

instead of
s3c2410-wdt s3c2410-wdt: watchdog active, reset enabled, irq enabled

Also it may completely disinform about irq status, as it prints
"irq enabled" when S3C2410_WTCON_INTEN is in fact 0.

Fix it.
