[PATCH] [PATCH net-next] net: sfp: add quirk for OEM SFP+ONU-XGSPON

[Romit Sagu]

This XGS-PON ONU stick (vendor OEM, part SFP+ONU-XGSPON)
needs the same handling as other Potron-based modules. Without it,
the module fails to connect and the kernal shows these errors:
sfp sfp1: module transmit fault indicated
sfp sfp1: module persistently indicates fault, disabling

This module requires TX_FAULT/LOS behaviour and boot delay tuning.
Add a quirk using the existing sfp_fixup_potron.
