A built-in scmi cpufreq driver cannot link against a modular thermal framework:
drivers/cpufreq/scmi-cpufreq.o: In function `scmi_cpufreq_ready': scmi-cpufreq.c:(.text+0x40): undefined reference to `of_cpufreq_cooling_register' drivers/cpufreq/scmi-cpufreq.o: In function `scmi_cpufreq_exit': scmi-cpufreq.c:(.text+0x88): undefined reference to `cpufreq_cooling_unregister' This adds a Kconfig dependency that makes sure this configuration is not possible, while allowing all configurations that can work. Note that disabling CPU_THERMAL means we don't care about the THERMAL dependency.
