KVM: s390: introduce defines for control registers
In KVM code we use masks to test/set control registers. Let's define the ones we use in arch/s390/include/asm/ctl_reg.h and replace all occurrences in KVM code. As we will be needing the define for Clock-comparator sign control soon, let's also add it. Suggested-by: Collin L.
