pc-bios/s390-ccw: Use proper register names for Clang



When compiling the s390-ccw firmware with Clang 7.0.1, I get the
following errors:

pc-bios/s390-ccw/start.S:62:19: error: invalid use of length addressing
        stctg 0,0,0(15)
                  ^

Let's use proper register names like in the rest of this file to fix it.
