Subject: [PATCH] thermal: rcar_thermal: Constify static thermal_zone_device_ops

The only usage of rcar_thermal_zone_of_ops is to pass its address to
devm_thermal_of_zone_register(), which takes a pointer to const struct
thermal_zone_device_ops. Make it const to allow the compiler to put
it in read-only memory.
