[U-Boot] [PATCH v2 26/32] dm: usb: Unbind old block devices when shutting down USB

[Simon Glass]

We don't want old block devices hanging around since they can still appear
visible in some way.

Possibly we should unbind all devices which don't cause problems by being
unbound. Most likely we can remove everything except USB controllers, hubs
and emulators. We can consider that later.
