ASoC: Intel: Skylake: Constify struct snd_soc_tplg_ops

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
  58844	   5282	     56	  64182	   fab6	sound/soc/intel/skylake/skl-topology.o

After:
   text	   data	    bss	    dec	    hex	filename
  59004	   5122	     56	  64182	   fab6	sound/soc/intel/skylake/skl-topology.o
