Phase 5: Fix MDEV creation blocker - mdev parent registration & ioctl-based vGPU type registration
- Implemented nv_vgpu_mdev_register_parent() using mdev_register_parent() API
with nv_vgpu_mdev_types array for proper mdev parent registration
- Added ioctl NV_VGPU_IOCTL_REGISTER_VGPU_TYPE for userspace vGPU type registration
- Created separate header nv-vgpu-vfio-interface-nvidia.h for nvidia.ko
with only extern declarations to avoid duplicate symbol exports
- Used KBUILD_EXTRA_SYMBOLS to provide only needed symbols (nvidia_vgpu_vfio_*)
- Updated create_mdev.sh to use correct mdev type names (pci-nvidia-vgpu-*)
- Updated load_vgpu_stack.sh to load open-iov-vfio.ko before nvidia.ko
Result: 4 mdev types now show available_instances=8, mdev creation successful
