The older southbridges supported by the lpc_ich driver do not provide memory-mapped space of the root complex. The driver correctly avoids computing the iomem address in this case, yet submits a zeroed resource request anyway (via mfd_add_devices()).
Remove the iomem resource from the resource array submitted to the mfd core for the older southbridges.
