This reverts commit 52f0b59ec6b780f2a3e162d5862b90b406fa4697.

The PowerPC 405 CPU is used by the PPE42 CPU which was added to
QEMU v10.2.  The PPE42 CPU is basically a stripped down version
of the PowerPC 405 CPU and is used by the Power9, Power10, and
Power11 CPUs as an embedded processor to handle various tasks.
Also, IBM has plans to use the PowerPC 405 CPU model within a
year to model the On Chip Controller (OCC), which has an embedded
PPC405 CPU.  Therefore, this patch removes the PowerPC 405 CPU
from the deprecated list.

Ah ! That would be a great extension of the PowerNV machines.
It should be feasible now since it's all PPC.

One day, an Aspeed machine might well find its place on the
same board too.
