  In some applications, the mtk-wdt requires the toprgu (TOP Reset
Generation Unit) to reset timer after system resets. Add optional
mediatek,reset-by-toprgu property to enable it.

Please fix the description...

The Top Reset Generation Unit (TOPRGU) generate reset signals
and distributes them to each IP. If present, the watchdog timer
will be reset by TOPRGU once system resets.
