[S390] move sysinfo.c from drivers/s390 to arch/s390/kernel
All in sysinfo.c is core kernel code and not driver code. So move it to arch/s390/kernel. Also includes some small cleanups. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
