s390x/3270: Add emulated terminal3270 device 



This is a basic implementation of the emulated ccw-attached 3270
called x-terminal3270, which provides visibility of the device in
the qemu monitor and guest. The x prefix indicates that this is
just an experimental implementation for the current stage. This
device will not be compiled until the basic functions are available.
