The Fritzbox 3490, 5490 and 7490 devices have a Renesas µPD720202 USB3 PCIe device, which requires an endian switch for PCIe slave devices. The flag and setting is not implemented in the available patches. Since adding this setting would break other devices, a DTB setting lantiq,switch-pcie-endianess is added for selective enablement.
