mlxsw: core_thermal: Constify struct thermal_zone_device_ops
'struct thermal_zone_device_ops' are not modified in this driver.
Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
While at it, also constify a struct thermal_zone_params.
On a x86_64, with allmodconfig:
