This will cause make to dive into the scu subdir multiple times.
All CONFIG_INTEL_SCU* symbols either select or depend on CONFIG_INTEL_SCU, so we
can dive into the subdir only once based on this.
Also the Makefile line for diving into subdirs should be kept together.
I'll fix both up while merging the series there is no need for
a new version.

Hans
