ASoC: TSCS42xx: make const array norm_addrs static, reduces object code size 

Don't populate the const array norm_addrs on the stack, instead make it
static.  Makes the object code smaller by over 230 bytes.  Also re-format
array data as the insertion of the static keywork made the first line
overly long.

Before:
   text	   data	    bss	    dec	    hex	filename
  53780	  34752	    256	  88788	  15ad4	linux/sound/soc/codecs/tscs42xx.o

After:
   text	   data	    bss	    dec	    hex	filename
  53461	  34840	    256	  88557	  159ed	linux/sound/soc/codecs/tscs42xx.o

(gcc version 7.2.0 x86_64)
