Well, since this is supposed to be a human readable description, I would
go even further and write "...device tree node of Power Management Unit
to...".

Considering location of this file, which is arm/samsung, I think this
name is pretty much clear. ARM PMU is a generic thing, so it couldn't
be placed here.

That's quite a lot of text for a label. pmu_syscon as in previous version
of this patch would look more sensible to me.
