Similar to some other IA platforms, Elkhart Lake too depends on the PMU register write to request transition of Dx power state.
Thus, we add the PCI_DEVICE_ID_INTEL_EHLLP to the list of devices that shall execute the ACPI _DSM method during D0/D3 sequence.

I think this has gone under your radar. Let me know if you want anything to be changed.
