ASoC: uniphier: make arrays mul and div static const, makes object smaller

Browse Source 
Don't populate the arrays mul and div on the stack but instead make them
static const. Makes the object code smaller by 4 bytes.

   text    data     bss     dec     hex filename
  16226    4984      64   21274    531a ./sound/soc/uniphier/aio-cpu.o

After:
   text    data     bss     dec     hex filename
  16062    5144      64   21270    5316 ./sound/soc/uniphier/aio-cpu.o

(gcc version 10.2.0)
