ALSA: hda/ca0132: make some const arrays static, makes object smaller 

Don't populate const arrays on the stack but instead make them
static. Makes the object code smaller by 57 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
 173256	  38016	    192	 211464	  33a08	sound/pci/hda/patch_ca0132.o

After:
   text	   data	    bss	    dec	    hex	filename
 172879	  38336	    192	 211407	  339cf	sound/pci/hda/patch_ca0132.o

(gcc version 10.2.0)
