Leave it.. We don't need it now.. that's how these kind of config options
are defined as they are disabled by default.

I had a similar concern.. Currently also we aren't stopping anybody to
enable boost. By selecting thermal from CPU_FREQ_BOOST_SW, atleast
we are communicating this very well to developers that they need
something else as well. And currently we only have thermal as a source
for telling when to block boost but it can be something else too..

I never said, don't use EXYNOS_THERMAL, its good to have a
dependency on it in the Exynos specific config for boost, but I wanted
normal sw boost also to depend on thermal..
