USB: serial: ftdi_sio: fix gpio name collisions
Drop the gpio line names, which cause gpiolib to complain loudly
whenever a second ftdi gpiochip is registered:
gpio gpiochip5: Detected name collision for GPIO name 'CBUS0'
gpio gpiochip5: Detected name collision for GPIO name 'CBUS1'
gpio gpiochip5: Detected name collision for GPIO name 'CBUS2'
gpio gpiochip5: Detected name collision for GPIO name 'CBUS3'
and also prevents the legacy sysfs interface from being used (as the
line names are used as device names whenever they are set):
sysfs: cannot create duplicate filename '/class/gpio/CBUS0'
Until non-unique names are supported by gpiolib (without warnings and
stack dumps), let's leave the gpio lines unnamed.
