From: Bjorn Helgaas <[email protected]>
Christian reported that f3ac2ff14834 ("PCI/ASPM: Enable all ClockPM and
ASPM states for devicetree platforms") broke booting on the A-EON X5000.
Override the L0s and L1 Support advertised in Link Capabilities by the
X5000 Root Ports ([1957:0451]) so we don't try to enable those states.
Fixes: f3ac2ff14834 ("PCI/ASPM: Enable all ClockPM and ASPM states for
devicetree platforms")
Fixes: df5192d9bb0e ("PCI/ASPM: Enable only L0s and L1 for devicetree
platforms")
