The commit 101c92dc80c8 ("PCI: mediatek: Set up vendor ID and class type for MT7622") have set the class ID for MT7622 as PCI_CLASS_BRIDGE_HOST, but it's not workable for MT7622: In __pci_bus_assign_resources, the framework only setup bridge's resource window only if class type is PCI_CLASS_BRIDGE_PCI. Or it will leave the subordinary PCIe device's MMIO window un-touched. Fixup the class type to PCI_CLASS_BRIDGE_PCI as most of the controller driver do.
