Constifying "struct snd_soc_tplg_ops" moves some data to a read-only
section, so increase overall security.

On a x86_64, with allmodconfig:
Before:
   text	   data	    bss	    dec	    hex	filename
  28046	    794	      0	  28840	   70a8	sound/soc/intel/avs/topology.o

After:
   text	   data	    bss	    dec	    hex	filename
  28206	    614	      0	  28820	   7094	sound/soc/intel/avs/topology.o
