USB: serial: ftdi_sio: add support for Altera USB Blaster 3

commit 18e0885bd2ca738407036434418a26a58394a60e upstream.

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 the support for various configurations of the on-board
USB Blaster 3 by including the appropriate VID/PID pairs,
allowing it to function as a serial device via ftdi_sio.

Note that this check-in does not include support for the
cable solution, as it does not support UART functionality.
The supported configurations are determined by the
hardware design and include:

1) PID 0x6022, FT2232, 1 JTAG port (Port A) + Port B as UART
2) PID 0x6025, FT4232, 1 JTAG port (Port A) + Port C as UART
3) PID 0x6026, FT4232, 1 JTAG port (Port A) + Port C, D as UART
4) PID 0x6029, FT4232, 1 JTAG port (Port B) + Port C as UART
5) PID 0x602a, FT4232, 1 JTAG port (Port B) + Port C, D as UART
6) PID 0x602c, FT4232, 1 JTAG port (Port A) + Port B as UART
7) PID 0x602d, FT4232, 1 JTAG port (Port A) + Port B, C as UART
8) PID 0x602e, FT4232, 1 JTAG port (Port A) + 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.
