6.6-stable review patch. If anyone has any objections, please let me know.

commit bd1f6a31e7762ebc99b97f3eda5e5ea3708fa792 upstream.
When dGPU is put into BOCO it may be in D3cold but still able send PME on display hotplug event. For this to work it must be enabled as wake source from D3.
When runpm is enabled use pci_wake_from_d3() to mark wakeup as enabled by default.
