This patch set introduces support for acpi-generic-initiator devices,
supported by QEMU [1].
The acpi-generic-initiator object is required to support Multi-Instance GPU
(MIG) configurations on NVIDIA GPUs [2]. MIG enables partitioning of GPU
resources into multiple isolated instances

Add documentation for the new element in hostdev,
which allows associating devices with ACPI Generic Initiator objects in
QEMU.
A typical use case is NVIDIA Multi-Instance GPU (MIG), where a physical
GPU is partitioned into multiple isolated instances, each tied to one or
more virtual NUMA nodes.
