ppc/pnv: Introduce PnvMachineClass::dt_power_mgt()
We add an extra node to advertise power management on some machines,
namely powernv9 and powernv10. This is achieved by using the
pnv_is_power9() and pnv_is_power10() helpers.
This can be achieved with QOM. Add a method to the base class for
powernv machines and have it implemented by machine types that
support power management instead.
