Subject: [PATCH] memory: tegra: Constify struct thermal_cooling_device_ops

The only usage of tegra210_emc_cd_ops is to pass its address to
devm_thermal_of_cooling_device_register() which is a pointer to const
struct thermal_cooling_device_ops. Make it const to allow the compiler
to put it in read-only memory.
