Janosch Frank 1cca826549 s390x: Add SIDA memory ops
Protected guests save the instruction control blocks in the SIDA
instead of QEMU/KVM directly accessing the guest's memory.

Let's introduce new functions to access the SIDA.

The memops for doing so are available with KVM_CAP_S390_PROTECTED, so
let's check for that.
