[PATCH] i386: Add new CPU model EmeraldRapids

ticable to define EMR as an alias of a new version of SPR by only updating the model number and model name, it loses the flexibility when new version of EMR cpu model are needed for adding new features (that hasn't virtalized/supported by KVM yet). So just add EMR as a standalone cpu model. Sign
