Currently, moving from a port on one LAN8814 PHY package to another results in a no traffic flowing on that new port. It was tracked down to upstream change that fixed the issue that QSGMII was soft reset on .config_init of each of 4 PHY-s in the package resulting in a temporary traffic loss until QSGMII resynced. However, it seems that the QSGMII soft reset timing is crucial and doing the reset during probe only cause the QSGMII link to become partially unsynced (Like 2 or 3 lanes are not synced). So, add an upstream patch[1] to fix this, patch was modified as we dont have the inband caps currently.
