[7/7] PCI: dwc: Prefer of_device_get_match_data() over of_device_device()

Commit Message

The dw_plat PCI controller driver only needs
"struct dw_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 dw_plat_pcie_of_data *" directly.
