RZQ is not optional

I have received the following update from Xilinx regarding the RZQ pin.


The RZQ pin is a “required” pin for the MCB interface.  The soft cal module uses this pin for some other functions, even if the user decides to leave it as a No Connect because they don’t plan to use "calibrated input termination."
