proc: remove ->get_info infrastructure

Now that last dozen or so users of ->get_info were removed, ditch it too.
Everyone sane shouldd have switched to seq_file interface long ago.

P.S.: Co-existing 3 interfaces (->get_info/->read_proc/->proc_fops) for proc
      is long-standing crap, BTW, thus
      a) put ->read_proc/->write_proc/read_proc_entry() users on death row,
      b) new such users should be rejected,
      c) everyone is encouraged to convert his favourite ->read_proc user or
         I'll do it, lazy bastards.
