[PATCH] ppc: Deprecate 'ref405ep' machine and 405 CPUs

[Cédric Le Goater]

The 'ref405ep' machine and PPC 405 CPU have no known users, firmware
images are not available, OpenWRT dropped support in 2019, U-Boot in
2017, Linux also is dropping support in 2024. It is time to let go of
this ancient hardware and focus on newer CPUs and platforms.
