These nodes are example nodes for the PCIe controller in "endpoint" mode.
By default the controller is in "root complex" mode and there is already a
DT node for the same.
Examples should go in the bindings or other documentation.
Remove this node.
How we will support EP from now onwards, using overlays ?
They are already disabled, how do you support them today?
