Replace legacy's reset call by device_reset_warm.

The new function propagates also the reset to the sub-buses tree.

In spapr_vio.c, the function resets a SpaprtceTable which does not seem
to have child bus so it should have no impact.

In Spapr_pci.c the functions resets QOM children devices of a SpaprPhbState.
If there is a device with a child bus, then this bus will now be reset
(and all its qdev tree).
