watchdog: orion: Make RSTOUT register a separate resource
In order to support other SoC, it's required to distinguish
the 'control' timer register, from the 'rstout' register
that enables system reset on watchdog expiration.
To prevent a compatibility break, this commit adds a fallback
to a hardcoded RSTOUT address.
