usb-host: add option to allow all resets.
Commit 65f14ab98da1 ("usb-host: skip reset for untouched devices") filters out multiple usb device resets in a row. While this improves the situation for usb some devices it doesn't work for others :-( So go add a config option to make the behavior configurable.
