Make more features optional

Browse Source 
Preparatory work to introduce a second SoC : 2nd series 3/4

Some modules won't be used on other designs, make them optional.

Signed-off-by: Vincent Palatin <vpalatin@chromium.org>

BUG=None
TEST=run the EC firmware on BDS and check that the commands from the
optional features are still available and working.
