Don't populate the array div on the stack but instead it
static const. Makes the object code smaller by 48 bytes.

Before:
   text    data     bss     dec     hex filename
  53894   16368     128   70390   112f6 ./sound/soc/codecs/rt5514.o

After:
   text    data     bss     dec     hex filename
  53750   16464     128   70342   112c6 ./sound/soc/codecs/rt5514.o

(gcc version 10.2.0)
