This adds the low-speed connector to the ZCU100 rev C device
tree (also known as the Ultra96 board).
This is a proof-of-concept only, showing how it is possible
to populate a Secure96 board using the other patches in the
series.
If you comment out or delete the board {} node, you can
populate/depopulate the board from sysfs instead.
