From: Honghui Zhang <honghui.zhang@xxxxxxxxxxxx>
The PCIe controller of MT7622 has TYPE 1 configuration space type, but
the HW default class type values is invalid.
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.
