The 'mdev' string now represents the absolute path to an
mdev device (/sys/bus/pci/devices/<addr>/<uuid>) instead
of the mdev_type directory for the mdev device
(/sys/bus/pci/devices/<addr>/mdev_supported_types/<mdev-type>).
This is more intuitive and will make it easier to get
more information about a particular mdev device -
like the driver or iommu_group it belongs to - which can
be found at /sys/bus/pci/devices/<addr>/<uuid>.
