A lot of what virtio_ccw_device_realize() does isn't specific to
virtio; it would apply to emulated CCW as well. Factor it out to make
it easier to implement emulated CCW devices later on.

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.

Move cpu_inject_* to the only C file where they are used.
Move ioinst.h declarations that need S390CPU to cpu.h, to make
ioinst.h independent of cpu.h.
Move channel declarations that only need SubchDev from cpu.h
to css.h, to make more channel users independent of cpu.h.
