sanity across guest reboot since caps are re-applied across reboots and

hw/ppc/spapr_hcall: Rename {softmmu -> vhyp_mmu}_resize_hpt_pr

Since 'softmmu' is quite a loaded term in QEMU, rename the vhyp MMU
facilities to use the vhyp_mmu_ prefix rather than softmmu_.

vhyp_mmu_ is chosen because the code that manipulates the hash table
via guest software hypercalls is QEMU's implementation of the PAPR
hypervisor interface, called vhyp.

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.

b392a1989170 ("vfio/pci: remove vfio_pci_nvlink2")

This was 2.5 years ago. Do the same in QEMU with a revert of commit
ec132efaa81f ("spapr: Support NVIDIA V100 GPU with NVLink2"). Some
adjustements are required on the NUMA part.

spapr: Fix record-replay machine reset consuming too many events

spapr_machine_reset gets a random number to populate the device-tree
rng seed with. When loading a snapshot for record-replay, the machine
is reset again, and that tries to consume the random event record
again, crashing due to inconsistent record

Fix this by saving the seed to populate the device tree with, and
skipping the rng on snapshot load.
