Both TI's AM65x (K3) and TI's K2 PCIe driver are implemented in pci-keystone. However Only K2 PCIe driver should use it's own pci_ops for configuration space accesses. But commit 10a797c6e54a ("PCI: dwc: keystone: Use pci_ops for config space accessors") used custom pci_ops for both AM65x and K2. This breaks configuration space access for AM65x platform. Fix it here.
