[kvm-unit-tests PATCH v5 03/10] s390x: cr0: adding AFP-register control bit

[Pierre Morel <pmorel@linux.ibm.com>]

While adding the definition for the AFP-Register control bit, move all
existing definitions for CR0 out of the C zone to the assmbler zone to
keep the definitions concerning CR0 together.

Signed-off-by: Pierre Morel <pmorel@linux.ibm.com>
