Peter Grehan adb947a67a Use PCI power-mgmt to reset a device if FLR fails.
A large number of devices don't support PCIe FLR, in particular
graphics adapters. Use PCI power management to perform the
reset if FLR fails or isn't available, by cycling the device
through the D3 state.

This has been tested by a number of users with Nvidia and AMD GPUs.
