soc/intel/alderlake: Hook up the OC watchdog
Hook up the OC watchdog common block and initialize it if requested.
TEST=Enable watchdog on MSI PRO Z690-A and see the platform resets
after some time. Enable the watchdog in driverless mode and see the
platform no longer resets and periodic SMI keeps feeding the watchdog.
