[U-Boot] [PATCH] Revert "rockchip: firefly: Add "usb start" to auto-start USB device"

[Kever Yang]

This reverts commit a1903c18db13e740e6bedb8955b3272dce5104e1.

It's really bad idea to add "usb start" in preboot, it will spend
a lot of time to scan usb bus, and most of people do not need this
feature.
