This development kit has an FT4232 on it with a custom USB VID/PID.
The FT4232 provides four UARTs, but only two are used. The UART 0
is used by the FlashPro5 programmer and UART 2 is connected to the
SmartFusion2 CortexM3 SoC UART port.
Note that the USB VID is registered to Actel according to Linux USB
VID database, but that was acquired by Microsemi.

V2: - Move the ID in ftdi_sio_ids.h to keep it sorted by VIDs
- Use the JTAG quirk to avoid binding channel 0, this is needed by
the Libero software, otherwise it cannot use the programmer.

Thanks for verifying that you do not want to bind to interface 0.
Judging from the above description, it seems we can do even even better
and only bind to interface 2 using
USB_DEVICE_INTERFACE_NUMBER()
since you only have one uart connected that you want to expose, right?

You can remove this comment (having it in the git history should be
sufficient), and just make this a "Microsemi (formerly Actel)" header.
