[PATCH v2 2/2] dt-bindings: watchdog: ti,davinci-wdt: convert to dtschema

[Kousik Sanagavarapu <five231003@gmail.com>]

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