Add power controller node for MT8192.
In scpsys node, it contains clocks and regmapping of
infracfg for bus protection.
And list all the power domains of MT8192 under scpsys node
to show the dependency between each other through hierarchical
structure.

Hi Weiyi,

First of all, thanks for your patch!
The actual scpsys driver has some limitations. Enric and I are working on a new
driver [1]. My idea is to deprecate the old scpsys driver in favor of this new one.
Would you mind to resend your series on top of [1]?
Regards,
Matthias
