pc-bios/s390-ccw: ISO-9660 El Torito boot implementation
This patch enables boot from media formatted according to
ISO-9660 and El Torito bootable CD specification.
We try to boot from device as ISO-9660 media when SCSI IPL failed.
The first boot catalog entry with bootable flag is used.
ISO-9660 media with default 2048-bytes sector size only is supported.
