First of all, excellent bug report and analysis of the issue.

> Why was the driver added in the first place?

Most likely because the phy driver is required to change the chip defaults RGMII delay mode settings.

> If that's the problem, then a better fix could be setting phy-mode to rgmii-id or rgmii-rxid in the dts

Would you please give the images from https://www.kresin.me/files/lede-17.01.2/targets/ramips/mt7620/ a try. One of them should fix the issue and I need to know which it is. The images should be completely compatible to the official LEDE 17.01.2 release.
