[POWERPC] iSeries: fix mf proc initialisation
This proc file should only be created if we are running on legacy iSeries. Since we can now run the same kernel on legacy iSeries and other machines, we currently get the /proc/iSeries directory and the files in it on non-iSeries machines, and accessing them causes an oops in some cases. This and the following patches make sure that these files are not created on non-iSeries machines, thus avoiding the oops.
