[S390] cio: Introduce abstract isc definitions.
Replace the numeric values for I/O interruption subclass usage with abstract definitions and collect them all in asm/isc.h. This gives us a better overview of which iscs are actually used and makes it possible to better spread out isc usage in the future.
