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.
