Hi,

this patch series contains at first a patch for the power domain subsystem
which offers to uninit generic power domains when init was called before.

The RPi Power-Domains need to be enabled/disabled by interacting with the
RPi firmware which can fail. To cleanup the probing we need to undo the
power domains again which was registered before.
