soc: ti: knav_qmss: Constify struct knav_range_ops

Browse Source 
'struct knav_range_ops' is not modified in these drivers.

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
   7498	   1193	      0	   8691	   21f3	drivers/soc/ti/knav_qmss_acc.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   7566	   1145	      0	   8711	   2207	drivers/soc/ti/knav_qmss_acc.o
