xpp driver release 1.1.0 (first part of commit)

* FPGA firmware now loaded from PC (for newer models)
* Driver for the FXO module
* Moved most userspace files to the subdirectory utils (see also next commit)
* Explicit license for firmware files
* Optionally avoid auto-registration
* Initializations parameters to chips given from userspace
* And did I mention bugfixes?
