The PRM (Power and Reset Module) has a register to enable and disable
the related power domain, so let's update the binding for that.

The PRM controller has currently only support for resets while the power
domains are still handled in the platform code.
Let's add basic power domain support to enable and disable a PRM
controlled power domain if configured in the devicetree. This can be
used for various hardware accelerators, and interconnect instances.
Further support can be added later on as needed for runtime configuration
based on domain-idle-states.

Thanks no more need for __maybe_unused with these patches actually,
so I'll just drop those from the series.

it for genpd. And with that change, we can now also drop the old unused

We can power off l4_abe domain when not in use when we configure it for
genpd. And with that change, we can now also drop the old unused legacy
platform data.
Note that we also need to now use "simple-pm-bus" instead of "simple-bus"
for PM runtime to get enabled for the bus.
