Andrey Skvortsov 587c3f8ebe imx_watchdog: always set minimal timeout in reset_cpu
The problem is that timeout bits in WCR register were leaved unchanged.
So previously set timeout value was applied and therefore 'reset'
command takes any value up to two minutes, depending on previous
watchdog settings, instead of minimal 0.5 seconds.
