PCI PM: Add function for checking PME status of devices
Add function pci_check_pme_status() that will check the PME status bit of given device and clear it along with the PME enable bit. It will be necessary for PCI run-time power management. Based on a patch from Shaohua Li <shaohua.li@intel.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
