Merge tag 'pull-vfio-20250908' of https://github.com/legoater/qemu into staging

vfio queue:

* Large refactor of the VFIO code to use QOM casts and follow the
  current coding style guidelines
* Removal of the deprecated vfio-platform, vfio-calxeda-xgmac and
  vfio-amd-xgbe devices
* Fail with error if dma_max_mappings limit is hit
* Added 'x-pci-class-code' property to vfio-user-pci device
* Added a new helper to retrieve a VFIOPCIDevice from a VFIODevice
* Fixed IGD OpRegion detection
