[U-Boot] [PATCH 2/2] config_distro_bootcmd.h: Remove unnecessary magic to avoid repeated USB scans

[Hans de Goede]

Now that "usb start" will only start usb if not already started, we can simply
call "usb start" whenever we (may) need access to usb devices, and it will only
actually scan the bus at the first call.
