xhci: Clear the host side toggle manually when endpoint is 'soft reset'
Main benefit of this is to get xhci connected USB scanners to work. Some devices use a clear endpoint halt request as a 'soft reset' even if the endpoint is not halted. This will clear the toggle and sequence on the device side. xHCI however refuses to reset a non-halted endpoint, so instead we need to issue a configure endpoint command on xHCI to clear its host side toggle and sequence, and get it in sync with the device side.
