Christophe Leroy d12f449958 watchdog: mpc8xxx_wdt: Reload the watchdog timer when enabling the watchdog ... [ Upstream commit 7dfd80f70ef00d871df5af7c391133f7ba61ad9b ] When the watchdog gets enabled with this driver, it leaves enough time for the core watchdog subsystem to start pinging it. But when the watchdog is already started by hardware or by the boot loader, little time remains before it fires and it happens that the core watchdog subsystem doesn't have time to start pinging it. Until commit 19ce9490aa ("watchdog: mpc8xxx: use the core worker function") pinging was managed by the driver itself and the watchdog was immediately pinged by setting the timer expiry to 0. So restore similar behaviour by pinging it when enabling it so that if it was already enabled the watchdog timer counter is reloaded.
