dt-bindings: PCI: mvebu: Add num-lanes property

Browse source

Controller driver needs to correctly configure PCIe link if it contains 1
or 4 SerDes PCIe lanes. Therefore add a new 'num-lanes' DT property for
mvebu PCIe controller. Property 'num-lanes' seems to be de-facto standard
way how number of lanes is specified in other PCIe controllers.
