s390: move ipl block and cmd line handling to early boot phase
To distinguish zfcpdump case and to be able to parse some of the kernel
command line arguments early (e.g. mem=) ipl block retrieval and command
line construction code is moved to the early boot phase.
"memory_end" is set up correctly respecting "mem=" and hsa_size in case
of the zfcpdump.
arch/s390/boot/string.c is introduced to provide string handling and
command line parsing functions to early boot phase code for the compressed
kernel image case.
