'struct thermal_zone_device_ops' are not modified in these drivers.
Constifying these structures 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, as an example:
Before:
======
text data bss dec hex filename
28116 5168 128 33412 8284 drivers/thermal/armada_thermal.o
After:
=====
text data bss dec hex filename
