RH-MergeRequest: 278: Full boot order support for s390x [Centos 10]
RH-Jira: RHEL-58153

RH-Commit: [14/23] 54bcccfb27e230494b492eede1e074732b4efc17 (thuth/qemu-kvm-cs9)
Currently, structures defined in both hw/s390x/ipl.h and pc-bios/s390-ccw/iplb.h
must be kept in sync, which is prone to error. Instead, create a new directory
at include/hw/s390x/ipl/ to contain the definitions that must be shared.
