cpufreq: mediatek: allow building as a module
The MT8173 cpufreq driver can currently only be built-in, but
it has a Kconfig dependency on the thermal core. THERMAL
can be a loadable module, which in turn makes this driver
impossible to build.
It is nicer to make the cpufreq driver a module as well, so
this patch turns the option in to a 'tristate' and adapts
the dependency accordingly.
The driver has no module_exit() function, so it will continue
to not support unloading, but it can be built as a module
and loaded at runtime now.
