From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Don't populate the arrays vcore_val, vpll_val and vaux_val on the
stack, instead make them static const. Makes the object code smaller
by over 370 bytes:
Before:
text data bss dec hex filename
6971 3248 64 10283 282b drivers/mfd/stw481x.o
After:
text data bss dec hex filename
6338 3504 64 9906 26b2 drivers/mfd/stw481x.o
