PCI/PME: Drop unused support for PMEs from Root Complex Event Collectors
Since we register pcie_pme_driver only for PCI_EXP_TYPE_ROOT_PORT, the PME driver never claims Root Complex Event Collectors. Remove unused code related to Root Complex Event Collectors. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
