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.
