This is intended as a temporary fix to unblock our partners which are 
using our legacy devices as we work on refactoring our clock drivers to 
support the driver model.

Once the clock drivers for our legacy devices (Stratix10, N5X, Arria10 
and CycloneV) are ready to support the APIs, we will clean up the code.

Thanks,
Alif
