[2/7] PCI: cadence: Prefer of_device_get_match_data() over of_match_device()

Commit Message

The cadence PCI controller driver only needs
"struct cdns_plat_pcie_of_data *" during probe(). Replace
of_match_device(), which returns "struct of_device_id *", with
of_device_get_match_data(), to get "struct cdns_plat_pcie_of_data *"
directly.
