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
  19942	    832	      0	  20774	   5126	sound/soc/qcom/qdsp6/topology.o

After:
   text	   data	    bss	    dec	    hex	filename
  20102	    652	      0	  20754	   5112	sound/soc/qcom/qdsp6/topology.o
