s390x/cpumodel: mepochptff: warn when no mepoch and re-align group init
The extended PTFF features (qsie, qtoue, stoe, stoue) are dependent on the multiple-epoch facility (mepoch). Let's print a warning if these features are enabled without mepoch. While we're at it, let's move the FEAT_GROUP_INIT for mepochptff down the s390_feature_groups list so it can be properly indexed with its generated S390FeatGroup enum.
