PCI: mediatek: Fix class type for MT7622 to PCI_CLASS_BRIDGE_PCI 

commit 101c92dc80 ("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.

Fixes: 101c92dc80 ("PCI: mediatek: Set up vendor ID and class type for MT7622")
