PCI/ASPM: Make Intel DG2 L1 acceptable latency unlimited
Intel DG2 discrete graphics PCIe endpoints advertise L1 acceptable exit
latency to be < 1us even though they can actually tolerate unlimited exit
latencies just fine. Quirk the L1 acceptable exit latency for these
endpoints to be unlimited so ASPM L1 can be enabled.
