soc: mediatek: pwrap: Constify some struct int[]

These arrays are 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:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  45528	   8532	     16	  54076	   d33c	drivers/soc/mediatek/mtk-pmic-wrap.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  52664	   1384	     16	  54064	   d330	drivers/soc/mediatek/mtk-pmic-wrap.o
