Add WDT controller into alias field. After that, WDT index, used to distinguish different WDT controllers in the driver, can be gotten by using of_alias_get_id dts API.
I feel it would be less brittle if we encode the mapping in the driver? Based on reg the driver can derive the watchdog index. That way there's no constraint on how the platform architect arranges the aliases for the watchdogs (if they define them at all). Andrew
