Therefore, remove our names as reviewers and mark these platforms as

Related question: Does *anybody* know how to still use the ref405ep or
taihu board in QEMU? We just got another ticket asking for the related
firmware image:
https://gitlab.com/qemu-project/qemu/-/issues/651
And if you google for 'ppc405_rom.bin', I only find pages where people
are asking basically the same question, e.g.:
https://lists.nongnu.org/archive/html/qemu-devel/2007-08/msg00252.html
(in 2007 already! And no answer)
https://github.com/Xilinx/qemu/issues/36 (in 2019, no answer)
https://lists.libreplanet.org/archive/html/qemu-ppc/2019-12/msg00263.html (in
2019, no answer about bios location)

Seems like the Linux kernel removed support for the 405ep board here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=548f5244f1064c9facb19c5e9
The EP405 board was removed because it was apparently based on the buggy
405GP processor (It was selecting option CONFIG_405GP).
AFAIU the EP405 board is different from the ref405ep. The ref405ep has a
405EP processor which is still supported, see
https://elixir.bootlin.com/linux/v5.15-rc3/source/arch/powerpc/kernel/cputable.c#L1300

... to me this all sounds like these 405 boards are pretty dead code in
QEMU right now, so if nobody has a clue how to use them, I'd suggest to
mark them as deprecated and remove them in a couple of releases?
