dt-bindings: PCI: designware: Remove the num-lanes from Required properties
The num-lanes is not a mandatory property, e.g. on FSL
Layerscape SoCs, the PCIe link training is completed
automatically based on the selected SerDes protocol, it
does not need the num-lanes to set-up the link width.

Currently it is both a Required and Optional property,
let's remove it from the Required properties.
