[PATCH v2 6/7] arm64: dts: mt8167: Properly describe the SoC watchdog

Currently mt8167 inherits its watchdog from the included mt8516 dtsi,
which in turn falls back on mt6589-wdt. However according to the data
sheet mt8167 has 15 sw resets instead of 12, and the reset bits are
different from mt6589.

Use the dedicated mediatek,mt8167-wdt compatible for the watchdog driver,
as it correctly describes the SoC resets.
