PCI/PM: Note that PME can be generated from D0
Per PCIe r5.0 sec 7.5.2.1, PME may be generated from D0, so update
Documentation/power/pci.rst to reflect that.

In particular, the capability of generating PMEs from D3cold is optional and depends on the presence of additional voltage (3.3Vaux) allowing the device to remain sufficiently active to generate a wakeup signal. |
