If no kernel IPL entry is specified, boot the bios and pass if available
device information for the first boot device (as given by the boot index).

The provided information will be used in the next commit from the BIOS.

S390: IPL: Use different firmware for different machines

We have a virtio-s390 and a virtio-ccw machine in QEMU. Both use vastly
different ways to do I/O. Having the same firmware blob for both doesn't
really make any sense.

Instead, let's parametrize the firmware file name, so that we can have
different blobs for different machines.

Lets move the code to setup IPL for external kernel
or via the zipl rom into a separate file. This allows to

- define a reboot handler, setting up the PSW appropriately
- enhance the boot code to IPL disks that contain a bootmap that
was created with zipl under LPAR or z/VM (future patch)
- reuse that code for several machines (e.g. virtio-ccw and virtio-s390)
- allow different machines to provide different defaults
