PCI: dwc: Use generic config accessors

Browse source

Now that all the platforms with custom config access handling define
their own pci_ops, let's split the default config accessors to use
different pci_ops for root and child buses. With this, we can use the
generic config accessors. The child bus accesses mainly require a
.map_bus() hook to reconfigure the iATU on each config space access.
