mfd: Allow multiple MFD cells with the same name
Provide basic support for MFDs having multiple cells of a given type with different IDs by adding an id to the mfd_cell structure and then adding that to the id passed in to mfd_add_devices(). As it stands this approach requires that MFDs using this feature deal with ensuring that there aren't any ID collisions resulting from multiple MFDs of the same type being instantiated. This needs to happen with the existing code too, but with this approach there is a knock on effect on the IDs for non-duplicated devices.
