PCI/ASPM: Avoid L0s and L1 on PA Semi [1959:a002] Root Ports

Christian reported that f3ac2ff ("PCI/ASPM: Enable all ClockPM and
ASPM states for devicetree platforms") broke booting on the A-EON AmigaOne
X1000.

Override the L0s and L1 Support advertised in Link Capabilities by the
X1000 Root Ports ([1959:a002]) so we don't try to enable those states.

Fixes: f3ac2ff ("PCI/ASPM: Enable all ClockPM and ASPM states for devicetree platforms")
Fixes: df5192d ("PCI/ASPM: Enable only L0s and L1 for devicetree platforms")
