The thermal driver is a standalone driver for monitoring SoC temperature by enabling thermal sensor, so it can be enabled even when CONFIG_CPU_FREQ is NOT set. So remove the dependency with CPU_THERMAL.
Add CONFIG_CPU_FREQ check for cpu-freq related operation in thermal driver to make thermal driver probe successfully when CONFIG_CPU_FREQ is NOT set.
