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)
