net: sfp: add mode quirk for GPON module Ubiquiti U-Fiber Instant

[ Upstream commit f0b4f847673299577c29b71d3f3acd3c313d81b7 ]

The Ubiquiti U-Fiber Instant SFP GPON module has nonsensical information
stored in its 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.

This change finally allows to detect and use SFP GPON module Ubiquiti
U-Fiber Instant on Linux system.

EEPROM content of this SFP module is (where XX is serial number):
