s390x/css: introduce property type for device ids
Let's introduce a CssDevId to handle device ids of the xx.x.xxxx type used for channel devices. This has some benefits: - We can use them in virtio-ccw and split the validity checks for a channel device id in general from the constraint checking within the virtio-ccw scope. - We can reuse the device id type for future non-virtio channel devices. While we're at it, improve the validity checks and disallow e.g. trailing characters.
