ARM: at91/dt: declare atmel,at91rm9200-st as a syscon
The system timer register range is used to handle three different functionalities: Periodic Interval Timer, Real Time Timer and watchdog. Declare it as a syscon to be able to get a regmap. Also declare it as a simple-mfd and its watchdog subnode. Finally, document the watchdog compatible string.
