openpower-p9: disable host watchdog

Hostboot currently does not have IPMI support enabled on P9
systems.  Therefore, we need to disable the host watchdog.

Temporary workaround to be removed with openbmc/openbmc#993.

+Subject: [PATCH] Temporarily disable watchdog support
+
+Hostboot does not support IPMI on P9 systems yet, so they do
+not send the watchdog updates.  Disable the watchdog until
+they support.
