mei: speed up the power down flow
When mei driver is powering down due to suspend or shutdown it will iterate over the mei client bus and disconnect each client device attached in turn. The power down flow consist of the link rest, which causes all clients get disconnected at once, hence the individual disconnection can be omitted and significantly reduce power down flow.
