Subject: [PATCH] PCI/PM: Note that PME can be generated from D0

From: Bjorn Helgaas <bhelgaas@...gle.com>

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

 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.
