[S390] Use diag308 subcodes 3 and 6 for reboot and dump when possible.
This patch fixes a problem with the following scenario:
1. Linux booted from DASD "A"
2. Reboot from DASD "B" using "/sys/firmware/reipl/ccw/device"
3. Reboot DASD "B"
Without this patch in step 3 on newer s390 systems under LPAR instead of
DASD "B", DASD "A" will be booted. The reason is that in step 2 we use CCW
reipl and in step 3 we use DIAG308 (subcode 3) reipl. DIAG308 does not
notice the CCW reipl and still thinks that it has to reboot DASD "A".
Before applying this fix, ensure to have MCF RJ9967101E or z9 GA3 base driver
installed.
