Akhila YS ae18e2543c dt-bindings: arm: atmel,at91rm9200-st: convert to DT schema
Convert System Timer binding to YAML format.
Changes during conversion:
- Add "#address-cells" and "#size-cells" to the properties and required as
  watchdog is defined as a child node to the timer parent node.
- Define watchdog as a pattern property along with unit address in
  examples.
