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.
