usb: dm: Make "usb info" use usb_for_each_root_dev()
The old dm "usb info" implementation has several issues:
1) NULL pointer deref when a bus has no children
2) Not showing usb devices on busses without an emulated root-hub (otg host)
3) Attempting to show devices on inactive busses
4) "usb info" Would cause some hosts to get re-probed something which only
"usb reset" should do
TL;DR: proper iterating over usb bus root devs is hard, use the helper
for it.
