PCI: mediatek: Fix class type for MT7622 to PCI_CLASS_BRIDGE_PCI
commit 101c92dc80c8 ("PCI: mediatek: Set up vendor ID and class type for MT7622") erroneously set the class type for MT7622 to PCI_CLASS_BRIDGE_HOST. The PCIe controller of MT7622 integrates a Root Port that 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 and set it to PCI_CLASS_BRIDGE_PCI to match the hardware implementation.
