contrib/firmware: add new adapter ANGIE's firmware/bitstream code
This is ANGIE's firmware and bitstream code. The 'Embeded C' code is based on the openULINK project. The hdl bitstream source code is for the spartan-6 FPGA included in ANGIE. Since ANGIE has a different microcontroller (EZ-USB FX2) than openULINK (EZ-USB AN2131), the registers file (reg_ezusb.h) has been changed completely, so are the descriptors, interruptions and the endpoints configuration.
