Commit 0934dddc6436 ("arm: a37xx: Update DTS files to version from upstream Linux kernel") ported Linux's device-tree files for Armada 3720 SOCs. This broke USB port on Turris MOX, because in Linux' DTS the bus voltage supply is described as a `phy-supply` property of connector node, a mechanism that is not supported in U-Boot yet.
For now, fix this by adding `vbus-supply` to usb3 node.

Btw, now I tested USB2.0 and USB3.0 ports on Espressobin v5 (another Armada 3720 board) and both are working fine in U-Boot. Therefore no USB fix is needed for Espressobin DTS file.
Dear Stefan, as with the network issue, could we get this to master ASAP?
