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

commit b399078f882b6e5d32da18b6c696cc84b12f90d5 upstream.

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.
