enum types are defined but not used. It would be better to convert all of these to #defines.
These are only the Xilinx values. Need to add the Intel values from
https://github.com/analogdevicesinc/hdl/blob/master/library/scripts/adi_intel_device_info_enc.tcl
The #define names need to include XILINX or INTEL.
