[PATCH 3/3] arm64: dts: mediatek: mt6797: fix wdt compatible and add reset-cells

[Roman Vivchar via B4 Relay]

From: Roman Vivchar <rva333@xxxxxxxxxxxxxx>

The TOPRGU reset bits on the mt6797 SoC do not match that of mt6589,
therefore they are not compatible [1].

Remove the deprecated mt6589 fallback for mt6797 and add reset-cells to
enable other peripherals to use the TOPRGU resets.
