When booting from USB peripheral boot, the bootrom will not properly deinit the MUSB controller, which doesn't clearly indicate an USB disconnection to the host and leaves U-Boot to deal with the state of the previous USB session.
On some host controller drivers (e.g. xhci_hcd), this ends up in a failure during set address, caused by the lack of proper disconnection notification.
Resetting the controller early in U-Boot notifies the host of the disconnection and doesn't hurt other use cases.
