'struct pmic_wrapper_type' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
45336 8724 16 54076 d33c drivers/soc/mediatek/mtk-pmic-wrap.o
After:
=====
text data bss dec hex filename
45528 8532 16 54076 d33c drivers/soc/mediatek/mtk-pmic-wrap.o
