for feature-rich (i.e. DM-based) TPL stages.

help
The clock subsystem adds a small amount of overhead to the image.
If this is acceptable and you have a need to use clock drivers in
SPL, enable this option. It might provide a cleaner interface to
setting up clocks within TPL, and allows the same drivers to be
used as U-Boot proper.
