Don't populate the read-only arrays div and pd on the stack,
instead make them static const. Makes the object code smaller by 210 bytes:
Before:
text data bss dec hex filename
2869 720 0 3589 e05 sound/soc/codecs/rl6231.o
After:
text data bss dec hex filename
2495 880 0 3375 d2f sound/soc/codecs/rl6231.o
