peci: npcm: Constify struct peci_controller_ops​ 



'struct peci_controller_ops' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   8003	    784	     48	   8835	   2283	drivers/peci/controller/peci-npcm.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   8003	    776	     48	   8827	   227b	drivers/peci/controller/peci-npcm.o
