ppc/pnv: Remove Power8E and Power8NVL CPUs

Power8E and Power8NVL were deprecated since QEMU 10.1, with
commit 264a604e7163 ("target/ppc: Deprecate Power8E and Power8NVL")

Remove the corresponding 8E and 8NVL CPU cores from spapr/pseries

Also, with no use of 8E and 8NVL, in powernv chips or spapr cores,
remove the CPU definitions for the cores
