Merge tag 'pull-ppc-20230918' of https://gitlab.com/danielhb/qemu into staging

ppc patch queue for 2023-09-18:

In this short queue we're making two important changes:

- Nicholas Piggin is now the qemu-ppc maintainer. Cédric Le Goater and
Daniel Barboza will act as backup during Nick's transition to this new
role.

- Support for NVIDIA V100 GPU with NVLink2 is dropped from qemu-ppc.
Linux removed the same support back in 5.13, we're following suit now.

A xive Coverity fix is also included.
