Currently the device tree node for the XICS interrupt controller is in
spapr_create_fdt_skel(). As part of consolidating device tree construction
to reset time, this moves it to a function called from spapr_build_fdt().
In addition we move the actual code into hw/intc/xics_spapr.c with the
rest of the PAPR specific interrupt controller code.
