cxgb4: Constify struct thermal_zone_device_ops

Browse Source 
'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.

On a x86_64, with allmodconfig:
