Subject: [PATCH v2] USB: serial: ftdi_sio: add support for Altera USB Blaster 3

The Altera USB Blaster 3, available as both a cable and an on-board
solution, is primarily used for programming and debugging FPGAs.

It interfaces with host software such as Quartus Programmer,
System Console, SignalTap, and Nios Debugger. The device utilizes
either an FT2232 or FT4232 chip.

Enabling support for various configurations of the USB Blaster 3
by including the appropriate VID/PID pairs, allowing it to function
as a serial device via ftdi_sio. The configurations are determined
by the hardware design and include:

1) PID 0x6020, FT2232, 1 JTAG port
2) PID 0x6021, FT2232, 2 JTAG ports
3) PID 0x6022, FT2232, 1 JTAG port + Port B as UART
4) PID 0x6023, FT2232, Cable USB-Blaster 3
5) PID 0x6024, FT4232, 1 JTAG port
6) PID 0x6025, FT4232, 1 JTAG port + Port C as UART
7) PID 0x6026, FT4232, 1 JTAG port + Port C, D as UART
8) PID 0x602e, FT4232, 1 JTAG port + Port B, C, D as UART

These configurations allow for flexibility in how the
USB Blaster 3 is used, depending on the specific needs of the
hardware design.
