PCI: Constify struct pci_ecam_ops

Browse source 
struct pci_ecam_ops is typically DT match table data which is defined to
be const. It's also best practice for ops structs to be const. Ideally,
we'd make struct pci_ops const as well, but that becomes pretty
invasive, so for now we just cast it where needed.
