From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>
Don't populate arrays on the stack but instead them static const.
Makes the object code smaller by 48 bytes.
Before:
text data bss dec hex filename
20938 916 104 21958 55c6 ./sound/soc/sh/rcar/core.o
After:
text data bss dec hex filename
20890 916 104 21910 5596 ./sound/soc/sh/rcar/core.o
gcc version 11.1.0)
