Subject: [PATCH] net: sfp: add quirk for ATS SFP-GE-T 1000Base-TX module

This copper module comes with broken TX_FAULT indicator which must be
ignored for it to work. Implement ignoring TX_FAULT state bit also
during reset/insertion and mute the warning telling the user that the
module indicates TX_FAULT.
