dumpconf: add new parameter 'SCP_DATA' for SCSI/NVMe/ECKD dump devices

Browse Source 
The new parameter 'SCP_DATA' can be used to pass additional kernel cmdline
parameters to a stand-alone SCSI/NVMe/ECKD dumper for debugging purposes.

Configuration example
=====================

ON_PANIC=dump_reipl
DUMP_TYPE=fcp
DEVICE=0.0.4711
WWPN=0x5005076303004711
LUN=0x4711000000000000
BOOTPROG=0
BR_LBA=0
SCP_DATA="dump_debug=6 ignore_loglevel earlyprintk=sclp panic_print=3"
