[PATCH 6.19 393/844] watchdog: imx7ulp_wdt: handle the nowayout option

[Sasha Levin]

From: Oleksandr Suvorov <cryosay@xxxxxxxxx>

[ Upstream commit d303d37ef5cf86c8c3b2daefd2a7d7fd8ca1ec14 ]

The module parameter `nowayout` indicates whether the watchdog should ever
be allowed to stop, but the driver currently ignores this option.

Pass the `nowayout` parameter to the watchdog core by setting the
WDOG_NO_WAY_OUT flag accordingly.
