powerpc/pseries: Handle and log pseries-wdt registration failures

Browse source

The pseries watchdog initialization registers the pseries-wdt platform
device using platform_device_register_simple(), but currently ignores
its return value.

Check the returned pointer for errors, log a descriptive error message
when registration fails, and propagate the failure code to the caller.
This avoids silently ignoring platform device registration failures.
