s390: provide sclp based boot console
Use the early sclp code to provide a boot console. This boot console is available if the kernel parameter "earlyprintk" has been specified, just like it works for other architectures that also provide an early boot console. This makes debugging of early problems much easier, since now we finally have working console output even before memory detection is running. The boot console will be automatically disabled as soon as another console will be registered.
