PCI: host-generic: Allow {en,dis}able_device() to be provided via pci_ecam_ops
In order to let host controller drivers using the host-generic
infrastructure use the {en,dis}able_device() callbacks that can be used to
configure sideband RID mapping hardware, provide these two callbacks as
part of the pci_ecam_ops structure.
