watchdog: menz069_wdt: fix timeout setting
When setting the timeout for the menz069_wdt watchdog driver, we
erroneously read from the 'watchdog value register' (WVR) instead of the
'watchdog timer register' (WTR) and then write the value back into WTR.
This can potentially lead to wrong timeouts and wrong enable bit settings.
