Revert "hw/ppc: Deprecate 405 CPUs"

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.
