This adds the CPUFreq driver support for Mediatek MT8173 SoC.

ARM_MT8173_CPUFREQ is a bool symbol, so mt8173-cpufreq.o will never be part of a module.
(If that's incorrect you can stop reading here.)

I guess this include is not needed. And, for what it's worth, make ARCH=arm CROSS_COMPILE=arm-linux-gnu- drivers/cpufreq/mt8173-cpufreq.o
compiles silently even if it's dropped.
+module_init(mt8173_cpufreq_driver_init);
According to include/linux/init.h, for built-in only code, this is equivalent to device_initcall([...]). And two runs of make ARCH=arm CROSS_COMPILE=arm-linux-gnu- drivers/cpufreq/mt8173-cpufreq.i
confirm that.
Thanks,
