Marcus Folkesson a1a63a270e watchdog: da9052_wdt: respect TWDMIN
[ Upstream commit 325f510fcd ]

We have to wait at least the minimium time for the watchdog window
(TWDMIN) before writings to the wdt register after the
watchdog is activated.
Otherwise the chip will assert TWD_ERROR and power down to reset mode.
