The PCIe controller of MT7622 is complexed with Root Port and PCI-to-PCI bridge, the bridge has type 1 configuration space header and related bridge windows. The HW default value of this bridge's class type is invalid. Fix its class type as PCI_CLASS_BRIDGE_PCI since it is HW defines. Making the bridge visiable to PCI framework by setting its class type properly will get its bridge windows configurated during PCI device enumerate.
