Two conversions to DT schema of GPIO watchdog binding happened and came through different trees. Merge them into one: 1. Combine maintainers, 2. Use more descriptive property descriptions and constraints from gpio-wdt.yaml, 3. Switch to unevaluatedProperties:false, to allow generic watchdog properties.
