cpufreq: Add ARM_MT8173_CPUFREQ dependency on THERMAL
If ARM_MT8173_CPUFREQ is configured, and THERMAL is configured as module,
the following build error is seen for arm:allmodconfig and
arm64:allmodconfig.
drivers/built-in.o: In function `mtk_cpufreq_ready':
:(.text+0x32a20c): undefined reference to `of_cpufreq_cooling_register'
drivers/built-in.o: In function `mtk_cpufreq_exit':
:(.text+0x32a420): undefined reference to `cpufreq_cooling_unregister'
The fix is similar to CPUFREQ_DT, but more restrictive since
ARM_MT8173_CPUFREQ can not be built as module.
