[PATCH] wifi: iwlwifi: Constify struct thermal_zone_device_ops

[Christophe JAILLET]

'struct thermal_zone_device_ops' is not modified in these drivers.

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

On a x86_64, with allmodconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  32535	   8657	    192	  41384	   a1a8	drivers/net/wireless/intel/iwlwifi/mvm/tt.o
  15212	   2872	    128	  18212	   4724	drivers/net/wireless/intel/iwlwifi/mld/thermal.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  32663	   8529	    192	  41384	   a1a8	drivers/net/wireless/intel/iwlwifi/mvm/tt.o
  15340	   2744	    128	  18212	   4724	drivers/net/wireless/intel/iwlwifi/mld/thermal.o
