pseries: Consolidate construction of /vdevice device tree node
Construction of the /vdevice node (and its children) is divided between
spapr_create_fdt_skel() (at init time), which creates the base node, and
spapr_populate_vdevice() (at reset time) which creates the nodes for each
individual virtual device.
This consolidates both into a single function called from
spapr_build_fdt().
