ASoC: intel: Constify struct snd_soc_ops

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

This structure is also part of scripts/const_structs.checkpatch.

As an example, on a x86_64, with allmodconfig:
Before:
   text	   data	    bss	    dec	    hex	filename
   6315	   3696	      0	  10011	   271b	sound/soc/intel/boards/ehl_rt5660.o

After:
   text	   data	    bss	    dec	    hex	filename
   6379	   3648	      0	  10027	   272b	sound/soc/intel/boards/ehl_rt5660.o
