pci_config_window keeps pointer to pci_ecam_ops and every time
we want to deallocate pci_config_window (pci_ecam_free()) we need to make
sure to free pci_ecam_ops in case it was dynamically allocated prior to
pci_ecam_create() call.
To avoid that extra effort, embed pci_ecam_ops in pci_config_window,
instead of just a pointer.
