Freedom Issue #3473
[hackrf] some files depend on nonfree software
Once downloaded we have the following in firmware/cpld/README:
This is a binary file built from HDL source in sgpio_if. You do not need
Xilinx tools unless you want to make your own modifications.
So the easiest way to fix this package is to generate a cleaned up tarball with the various firmwares removed and also not ship the firmwares unless we build them ourselves.
