This patch adds a property "mediatek,toprgu" in example so that we could
use reset controller(usually we call it toprgu or watchdog) to reset audio
domain regs.

As mentioned in the other patch, since this is reset controller,
you should use Documentation/devicetree/bindings/reset/reset.txt
instead.
