target/ppc: Introduce macro for deprecating PowerPC CPUs
QEMU has a way to deprecate CPUs by setting the 'deprecation_note' in
CPUClass.
Currently PowerPC CPUs don't use this deprecation process.
Introduce 'POWERPC_DEPRECATED_CPU' macro to deprecate particular PowerPC
CPUs in future.
With the change, QEMU will print a warning like below when the
deprecated CPU/Chips are used (example output if power8nvl is deprecated):
$ ./build/qemu-system-ppc64 -M powernv8 --cpu power8nvl -nographic
qemu-system-ppc64: warning: CPU model power8nvl_v1.0-powerpc64-cpu is deprecated -- CPU is unmaintained.
...
Also, print '(deprecated)' for deprecated CPUs in 'qemu-system-ppc64
--cpu ?' (example output if power8nvl is deprecated):
$ ./build/qemu-system-ppc64 --cpu help
...
power8e (alias for power8e_v2.1)
power8nvl_v1.0 PVR 004c0100 (deprecated)
power8nvl (alias for power8nvl_v1.0)
power8_v2.0 PVR 004d0200
...
