Previous, U-boot did not set fsl,liodn for rapidio in device tree, which is needed by HV(hypervisor), and HV needs fsl,liodn of rapidio have more values, for ex for P4080, fsl,liodn = <198 199 200>; while P2040/P3041/P5020 has 4 LIODNs respectivelly.
This patch using a generic mechanism which allow a device have mutilple liodns.
