[S390] cio: move scsw helper functions to header file
All scsw helper functions are very short and usage of them shouldn't result in function calls. Therefore we move them to a separate header file. Also saves a lot of EXPORT_SYMBOLs. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
