Tero Kristo ba54ddabc0 watchdog: reset last_hw_keepalive time at start 
[ Upstream commit 982bb70517 ]

Currently the watchdog core does not initialize the last_hw_keepalive
time during watchdog startup. This will cause the watchdog to be pinged
immediately if enough time has passed from the system boot-up time, and
some types of watchdogs like K3 RTI does not like this.

To avoid the issue, setup the last_hw_keepalive time during watchdog
startup.
