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 Reviewed-by: Philippe Mathieu-Daudé <philmd@oss.qualcomm.com> Tested-by: Misbah Anjum N <misanjum@linux.ibm.com> Signed-off-by: Aditya Gupta <adityag@linux.ibm.com> Link: https://lore.kernel.org/qemu-devel/20260703085955.2318600-8-adityag@linux.ibm.com Signed-off-by: Harsh Prateek Bora <harshpb@linux.ibm.com>
