[S390] pm: con3270 power management callbacks.
Introduce the power management callbacks to the 3270 driver. On suspend the current 3270 view is deactivated and for non-console 3270 device the release callback is done. This disconnects the current tty / fullscreen application from the 3270 device. On resume the current view is reactivated, on the tty you get a fresh login. If the system panics before the 3270 device has been resumed, the ccw device for the 3270 console is reactivated with ccw_device_force_console.
