List IOMMU groups with their PCIe devices and USB controllers

A hardware inspection utility that shows the relationships between IOMMU groups, physical PCIe hardware, and nested USB buses. It is commonly used when setting up Kernel-based Virtual Machines (KVM) with VFIO hardware passthrough (i.e., PCIe passthrough of a host device, such as a graphics card or a network interface) to a guest VM.
