wspoon: Increase watchdog timeout
Increasing the watchdog timeout to 10sec to allow dynamic fan speed
changes to continue until a BMC performance issue is resolved.
The watchdog wasn't being pinged within the original 3 seconds. This
would cause the fans to run at 100% PWM and eventually be marked
nonfunction resulting in a system being shutdown.
Temporarily, marking a fan nonfunctional when it's tach feedback speed
is above the target speed for witherspoon has been removed. This would
keep the system from being shutdown, however the fans are no longer
under dynamic speed control after the watchdog trips. Increasing the
watchdog timeout to 10sec prolongs dynamic fan speed control staying
active. If the watchdog trips, issuing a reboot will allow dynamic fan
speed control again.
