ASoC: codecs: ad193x: make two arrays static const, makes object smaller

Browse Source 
Don't populate the arrays on the stack but instead make them
static const. Makes the object code smaller by 37 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  16253	   7200	      0	  23453	   5b9d	sound/soc/codecs/ad193x.o

After:
   text	   data	    bss	    dec	    hex	filename
  16056	   7360	      0	  23416	   5b78	sound/soc/codecs/ad193x.o

(gcc version 9.2.1, amd64)
