chipset_enable: Add Kaby Lake U Prem. to known and tested systems

Intel Kaby Lake U (with the 9d4e device id) support is available but
marked not tested.

Tested reading, writing and erasing both internal flash chips on the
Facebook Monolith system with the Intel i3 7100U SoC. However, since all
ME-enabled chipsets are marked as DEP instead of OK, this one shall follow
suit as well.
