OMAP: common: consolidate fake USB ethernet MAC address creation
TI platforms such as OMAP5uevm, PandaBoard, use equivalent logic to generate fake USB MAC address from device unique DIE ID. Consolidate this to a generic location such that other TI platforms such as BeagleBoard-XM can also use the same. NOTE: at this point in time, I dont yet see a need for a generic dummy ethernet MAC address creation function, but if there is a need in the future, this can be further abstracted out.
