Add GPIO extender initial configuration that is needed to configure
some important GPIOs and ensure that the dev board is ready to work.
Add i2c_write function that make a write transfer to any slave device.
Give a new Product ID to ANGIE to make it different than the non
programmed ANGIE.

We want to keep the tri-state buffers located between the FPGA
and the board, in 'Z' state until we launch an i2c connection.
We launch an i2c start condition, make the SCL
direction 'OUT' to start the i2c protocol and at the end
of the i2c connection at the stop condition, we re-make
the tri-state buffers at 'Z' state.

add new i2c bit-banging feature, we can now connect in JTAG with the SoC
target and in i2c with the main board components at the same time.

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.
