s390x: Rebuild IPLB for SCSI device directly from DIAG308

Because virtio-scsi type devices use a non-architected IPLB pbt code they cannot
be set and stored normally. Instead, the IPLB must be rebuilt during re-ipl.

As s390x does not natively support multiple boot devices, the devno field is
used to store the position in the boot order for the device.

Handling the rebuild as part of DIAG308 removes the need to check the devices
for invalid IPLBs later in the IPL.

hw/s390x: Build an IPLB for each boot device

Build an IPLB for any device with a bootindex (up to a maximum of 8 devices).

The IPLB chain is placed immediately before the BIOS in memory. Because this
is not a fixed address, the location of the next IPLB and number of remaining
boot devices is stored in the QIPL global variable for possible later access by
the guest during IPL.

s390x: Add individual loadparm assignment to CCW device

Add a loadparm property to the VirtioCcwDevice object so that different
loadparms can be defined on a per-device basis for CCW boot devices.

s390x: Add individual loadparm assignment to CCW device

Add a loadparm property to the VirtioCcwDevice object so that different
loadparms can be defined on a per-device basis for CCW boot devices.

The machine/global loadparm is still supported. If both a global and per-device
loadparm are defined, the per-device value will override the global value for
that device, but any other devices that do not specify a per-device loadparm
will still use the global loadparm.

It is invalid to assign a loadparm to a non-boot device.
