ipmi-watchdog: Don't disable at shutdown

The op-build linux kernel has been configured to support the ipmi
watchdog. This driver will always handle the watchdog by either leaving
it enabled if configured, or by disabling it during module load if no
configuration is provided. This increases the coverage of the watchdog
during the boot process. The watchdog should no longer be disabled at
any point during skiboot execution.
