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. Link: https://lore.kernel.org/r/20191016194450.68959-1-helgaas@kernel.org Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

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.
