Please don't store all Apple-related bindings in bindings/arm/apple, but
instead group per device type like in most of other bindings. In this
case - this looks like something close to power domain controller, so it
should be in bindings/power/

This is a controller that, right now, is only used to instantiate device 
power management controls, but the controller itself is just a generic 
syscon device. Depending on the register range, it could conceivably 
encompass other register types (e.g. clock selects) within it, though 
I'm not sure I want to do that right now. Apple calls several of these 
different register sets as a whole a "PMGR". So I'm not sure if it 
really qualifies as "just" a power domain controller. If we want to 
restrict this to the power state portion of PMGR, then it might make 
sense to call it something more specific...

See arm/rockchip/pmu.yaml for the setup this is modeled after.

Makes sense now and actually few other designs including Samsung Exynos
have it as well.
