s390/early: use system_ctl_set_bit() instead of local_ctl_set_bit()
Use system_ctl_set_bit() instead of local_ctl_set_bit() to reflect
that the control register changes are supposed to be global. This
change is just for documentation purposes, since it still results only
in local control register contents being changed.
