hw/phb3/naples: Disable D-states
Putting "Mellanox Technologies MT27700 Family [ConnectX-4] [15b3:1013]"
(more precisely, the second of 2 its PCI functions, no matter in what
order) into the D3 state causes EEH with the "PCT timeout" error.
This has been noticed on garrison machines only and firestones do not
seem to have this issue.
This disables D-states changing for devices on root buses on Naples by
installing a config space access filter (copied from PHB4).
