The Ubiquiti U-Fiber Instant SFP GPON module has nonsensical
information stored in int EEPROM. It claims to support all transceiver
types including 10G Ethernet. Clear all claimed modes and set only
1000baseX_Full, which is the only one supported.

This module has also phys_id set to SFF, and the SFP subsystem
currently does not allow to use SFP modules detected as SFFs. Add
exception for this module so it can be detected as supported.
