dt-bindings: watchdog: Add compatible for MediaTek mt8167

Browse Source 
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 toprgu is not actually compatible with mt6589 (it has 14 sw
resets instead of 12, and its reset bit map table is different from
mt6589).

Update the mtk-wdt binding to add a dedicated compatible for mt8167 and
add the IDs that can be used in device trees to identify subsystem resets.
