QEMU emulates a *lot* of PowerPC-based machines - having a CPU
that is named "default" and cannot be used with most of those
machines sounds just wrong. Thus let's remove this old and confusing
alias now.

Do we need to document this in removed-features.rst ?

Honestly, I don't think that anybody ever really used this in the past 15 years. It was likely used with the "prep" machine, but we removed that one a couple of years already. The only machine that is still using this class of PowerPC CPUs is its successor, the 40p machine, but it has a 604 by default anyway, and I've never seen anybody using "-cpu default" with that machine. So IMHO it's not necessary to document this - but if people here have a different feeling, then I can also respin the patch, just let me know.
