  s390x: sigp: Force Set Architecture to return Invalid Parameter

According to the Principles of Operation, the SIGP Set Architecture
order will return Incorrect State if some CPUs are not stopped, but
only if the CZAM facility is not present. If it is, the order will
return Invalid Parameter because the architecture mode cannot be
changed.

Since CZAM always exists when S390_FEAT_ZARCH exists, which in turn
exists for every defined CPU model, we can simplify this code.

  s390x/kvm: step down as maintainer

I'm no longer involved with KVM/s390 on the kernel side, and I don't
have enough resources to work on the s390 KVM cpus support, so I'll
step down.

  s390x virtio-ccw machine: step down as maintainer

I currently don't have time to work on the s390x virtio-ccw machine
anymore, so let's step down. (I will, however, continue as a
maintainer for the virtio-ccw *transport*.)

  dtc: Update to version 1.6.1

The dtc submodule is currently pointing to non-release commit. It's nicer
if submodules point to release versions instead and since dtc 1.6.1 is
available now, let's update to that version.
