net: sfp: extend Potron XGSPON quirk to cover additional EEPROM variant

Some Potron SFP+ XGSPON ONU sticks are shipped with different EEPROM
vendor ID and vendor name strings, but are otherwise functionally
identical to the existing "Potron SFP+ XGSPON ONU Stick" handled by
sfp_quirk_potron().

These modules, including units distributed under the "Better Internet"
branding, use the same UART pin assignment and require the same
TX_FAULT/LOS behaviour and boot delay. Re-use the existing Potron
quirk for this EEPROM variant.
