dsa: Move tagger name into its ops structure

Browse source 
Rather than keep a list to map a tagger ops to a name, place the name
into the ops structure. This removes the hard coded list, a step
towards making the taggers more dynamic.

v2:
Move name to end of structure, keeping the hot entries at the beginning.
