The platform data of MT8186 is different from previous MediaTek SoCs,
so we add a new compatible and platform data for it.

There's no upstream DT for MT8186, so I"m curious how this was
tested/valiated with upstream?

Hello Kevin,

Thanks for your review.
The series of MT8186 DTS is still upstreaming.
From Matthias's comment, he will review MT8186 DTS series after clock
series is accepted.

We just now test MT8186 cpufreq on chromeos kernel v5.15.

MT8186 DTS series:

BRs,
