Alexander Usyskin 557909e195 mei: exclude device from suspend direct complete optimization
MEI device performs link reset during system suspend sequence.
The link reset cannot be performed while device is in
runtime suspend state. The resume sequence is bypassed with
suspend direct complete optimization,so the optimization should be
disabled for mei devices.
