You define these also in DTSI, so skip them.

I cannot get the point of these pin configurations - three groups with
only function difference. How this would be used by the driver? Maybe
just keep the one really used. Same for others below.

We have macros for these. Sam was using them for Exynos850, so I expect
the values have the same meaning also in Exynos7885. Use them please.

Wrong compatible. Please use specific, although I don't know which one
you have - 53 or 73... since you have two clusters, I would expect two
PMUs, hmm....
