- Rebase ppc64le QEMU backend support onto upstream v5: keep boot-order
generation off on pseries (avoids the SLOF once=d trap), add BOOTFROM=d
one-shot CD boot opt-in, and skip audio on ppc64le (EL9 QEMU has no
audio device model). Verified against EL9 qemu-kvm 10.1.
- Drop obsolete multifd patch (implemented upstream, auto-enabled for
QEMU >= 9.1) and the old combined AArch64/ppc64le patch.
- Carry Fedora backports: script_run serial marker (PR #2952) and
qemu 11 linuxboot.bin test fix (PR #2953).
