generic: add quirk for HG MXPD-483II 2500M fiber SFP

Browse Source 
The HG MXPD-483II 1310nm SFP module is meant to operate with 2500Base-X,
however, in their EEPROM they incorrectly specify:
    Transceiver type                          : Ethernet: 1000BASE-LX
    ...
    BR, Nominal                               : 2600MBd

Use sfp_quirk_2500basex for this module to allow 2500Base-X mode anyway.
