[kvm-unit-tests,0/2] s390x: smp: Improve setup of additional cpus

Let's not use constants for the PSW mask and CRs, but set them from
input data or cpu 0.

Later on we could add functions that take a ptr for setting up CRs of
additional cpus, but for now using the CRs 0,1,7,13 from cpu 0 will at
least result in a working DAT environment.
