v2 of this series is only a single patch which adds a new script to print the
segment:bus:device.function numbers of PCI devices on the user's system which
have a VFIO selftest driver. 

Example:
$ ./tools/testing/selftests/vfio/scripts/list_devices.sh
0000:6a:01.0
0000:6f:01.0
0000:74:01.0

The devices are compatible with all VFIO selftests. Other devices may be
compatible with VFIO selftests that don't use the driver functionality, but no
gaurantees.

User's can automate binding devices to VFIO (which is required in order to run
the selftests) by directing the output of list_devices.sh into
tools/testing/selftests/vfio/scripts/setup.sh.

Example:
$ ./tools/testing/selftests/vfio/scripts/setup.sh $(./tools/testing/selftests/vfio/scripts/list_devices.sh)
+ echo "0000:6a:01.0" > /sys/bus/pci/drivers/vfio-pci/unbind
+ echo "" > /sys/bus/pci/devices/0000:6a:01.0/driver_override
+ echo "0000:6a:01.0" > /sys/bus/pci/drivers/idxd/bind
+ echo "0000:6f:01.0" > /sys/bus/pci/drivers/vfio-pci/unbind
+ echo "" > /sys/bus/pci/devices/0000:6f:01.0/driver_override
+ echo "0000:6f:01.0" > /sys/bus/pci/drivers/idxd/bind
+ echo "0000:74:01.0" > /sys/bus/pci/drivers/vfio-pci/unbind
+ echo "" > /sys/bus/pci/devices/0000:74:01.0/driver_override
+ echo "0000:74:01.0" > /sys/bus/pci/drivers/idxd/bind

This series is based on top of the kvm/queue branch.

Changes from v1:
---
- Move the functionality to discover devices from setup.sh into its own script (Sean)
