[PATCH v7 2/9] PCI: mediatek: Fix class type for MT7622 as PCI_CLASS_BRIDGE_PCI

[honghui.zhang]

From: Honghui Zhang <honghui.zhang@xxxxxxxxxxxx>

The commit 101c92dc80c8 ("PCI: mediatek: Set up vendor ID and class
type for MT7622") have set the class type for MT7622 as un-properly
value of PCI_CLASS_BRIDGE_HOST.

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.
