Some PCI device devicetree is like: ```dts pcie@fe270000 { device_type = "pci"; msi-map = <0x1000 0x9c 0x1000 0x1000>; pcie@10 { reg = <0x100000 0x00 0x00 0x00 0x00>; #address-cells = <0x03>; #size-cells = <0x02>; pcie@10,0 { reg = <0x00 0x00 0x00 0x00 0x00>; }; }; }; ``` that the pcie@10,0 have a private ofw node, it will find property name `msi-map` or `msi-parent` fail. We should only find the property in host bridge's ofw node. Signed-off-by: GuEe-GUI <2991707448@qq.com>
