hw/ppc: Deprecate 405 CPUs

Browse source 
The ref405ep machine is scheduled for removal in QEMU 10.0. Keep the
405 CPU implementation for a while because it is theoretically
possible to model the power management (OCC) co-processor found on the
IBM POWER [8-11] processors.

PPC 405 CPUs (since 10.0)
'''''''''''''''''''''''''
The PPC 405 CPU has no known users and the ``ref405ep`` machine was
removed in QEMU 10.0. Since the IBM POWER [8-11] processors uses an
embedded 405 for power management (OCC) and other internal tasks, it
is theoretically possible to use QEMU to model them. Let's keep the
CPU implementation for a while before removing all support.
