net: sfp: add quirk for Potron SFP+ XGSPON ONU Stick
Add quirk for Potron SFP+ XGSPON ONU Stick (YV SFP+ONT-XGSPON).
This device uses pins 2 and 7 for UART communication, so disable
TX_FAULT and LOS. Additionally as it is an embedded system in an
SFP+ form factor provide it enough time to fully boot before we
attempt to use it.
