Johan Hovold 163cc462de gpib: lpvo_usb: fix unintended binding of FTDI 8U232AM devices
The LPVO USB GPIB adapter apparently uses an FTDI 8U232AM with the
default PID, but this device id is already handled by the ftdi_sio
serial driver.

Stop binding to the default PID to avoid breaking existing setups with
FTDI 8U232AM.

Anyone using this driver should blacklist the ftdi_sio driver and add
the device id manually through sysfs (e.g. using udev rules).

Fixes: fce79512a9 ("staging: gpib: Add LPVO DIY USB GPIB driver")
Fixes: e6ab504633 ("staging: gpib: Destage gpib")
