USB: serial: ftdi_sio: add support for Abacus Electrics Optical Probe

Abacus Electrics makes optical probes for interacting with smart meters
over an optical interface.

At least one version uses an FT232B chip (as detected by ftdi_sio) with
a custom USB PID, which needs to be added to the list to make the device
work in a plug-and-play fashion.
