ppc: Simplify reverse dependencies of POWERNV and PSERIES on XICS and XIVE

Have PSERIES to select XICS and XIVE, and directly check PSERIES
in hw/intc/meson.build to enable build of the XICS and XIVE sPAPR
backends, like POWERNV already does. This allows to get rid of the
intermediate XICS_SPAPR and XIVE_SPAPR.
