Subject: [PATCH v14 0/1] Add basic node support for MediaTek MT8186 SoC

MT8186 is a SoC based on 64bit ARMv8 architecture. It contains 6 CA55
and 2 CA76 cores. MT8186 share many HW IP with MT65xx series. This
patchset was tested on MT8186 evaluation board to shell. This series
is based on tag: tag: next-20220811, origin/master

Since we have a another dts series of mt8195[1] which is waiting for
review from maintainers. we remove power domains controller node from
this mt8186 series and because the power domains controller is required
for dsi, we also need to remove dsi node. Those will be updated on another
patchi in the feature.

Based on Comments in [2], we use "mediatek,mt8186-wdt", "mediatek,mt6589-wdt"
instead of "mediatek,mt8186-wdt" according to bindings definition.

There is a correction in mt8186 hardware bindings. We need to apply it
[3].
