s390x/ipl: Support IPL from selected SCSI device
If bootindex is specified for a device, we need to IPL from
it. Currently it works for ccw devices, but not for SCSI. To be able to
IPL from the specific device, pc-bios needs to know its address.
For this reason we add special QEMU_SCSI IPL type into the IPLB
structure, that contains the scsi device address.
We enhance the ipl block with a currently qemu-only parameter block
that allows us to specify a concrete scsi device.
