dt-bindings: watchdog: ti,davinci-wdt: convert to dtschema

Convert txt bindings of TI's DaVinci/Keystone Watchdog Timer Controller
to dtschema to allow for validation.

While at it,
- Change the order of the compatibles.
- Add "power-domains" to represent that the power domain maybe managed by
TI-SCI controller if found on the SoC (for example, Keystone based K2G).

w.r.t. to the txt binding to stay in sync with existing DTS.
