I see some serious design problems with multiple entries in power domains
property. First how to show that some part of the device IS NOT in
any domain?

Is that even possible? Every device should be in some power
domain, even if it's just an "always on" power domain that we
don't really control from software.

Right now none dts of which I'm aware of doesn't define the power domain for
the parts of the SoC, which are always on and doesn't need any additional
management.

Actually there's is one reason for doing this, as it would allow
devices to be monitored for device PM QoS constraints by the genpd
governor.

Although, I doubt's someone actually does it because of this benefit,
at least yet.
