Interesting, I wonder if the references to these have accidentally been 
dropped at some point, namely (in 2012?) when we converted the clocks to 
use common clock struct.

Anyway, I guess we can fix the ssi/usb clocks later if we find some 
issues with them, its been at least 3 years since these have been used.
