commit f331a859e0 upstream.
Enable a mechanism for devices to quirk that they do not behave when
doing a PCI bus reset. We require a modest level of spec compliant
behavior in order to do a reset, for instance the device should come
out of reset without throwing errors and PCI config space should be
accessible after reset. This is too much to ask for some devices.
