[S390] pm: dasd power management callbacks.
Introduce the power management callbacks to the dasd driver. On suspend the dasd devices are stopped and removed from the focus of alias management. On resume they are reinitialized by rereading the device characteristics and adding the device to the alias management. In case the device has gone away during suspend it will caught in the suspend state with stopped flag set to UNRESUMED. After it appears again the restore function is called again.
