Several GPON ONT SFP sticks based on Realtek RTL960x report
1000BASE-LX at 1300MBd in their EEPROM but can operate at 2500base-X.
On hosts capable of 2500base-X (e.g. Banana Pi R3 / MT7986), the
kernel negotiates only 1G because it trusts the incorrect EEPROM data.

Add quirks for:
- Hisense-Leox LXT-010S-H
- Hisense ZNID-GPON-2311NA
- HSGQ HSGQ-XPON-Stick

Each quirk advertises 2500base-X and ignores TX_FAULT during the
module's ~40s Linux boot time.

Tested on Banana Pi R3 (MT7986) with OpenWrt 25.12.1, confirmed
2.5Gbps link and full throughput with flow offloading.

Changes in v3:
  - Fix inaccurate commit message: the MT7986 SerDes is not fixed at
    2500base-X; it also supports 1000base-X and SGMII. Corrected to
    state that the kernel negotiates only 1G because it trusts the
    incorrect EEPROM data.
Changes in v2:
  - Add Suggested-by tag for Marcin Nita <marcin.nita@leolabs.pl>, who
    suggested investigating sfp.c quirks as a solution rather than
    attempting to edit the EEPROM data directly on the module.
