Subject: [PATCH 3/7] dt-bindings: pci: layerscape-pci: Add a optional property big-endian

From: Hou Zhiqiang <Zhiqiang.Hou@....com>

This property is to indicate the endianness when accessing the
PEX_LUT and PF register block, so if these registers are
implemented in big-endian, specify this property.
