  PPC: Unify dcbzl code path

The bit that makes a dcbz instruction a dcbzl instruction was declared as
reserved in ppc32 ISAs. However, hardware simply ignores the bit, making
code valid if it simply invokes dcbzl instead of dcbz even on 750 and G4.

Thus, mark the bit as unreserved so that we properly emulate a simple dcbz
in case we're running on non-G5s.

While at it, also refactor the code to check the 970 special case during
runtime. This way we don't need to differenciate between a 970 dcbz and
any other dcbz anymore. We also allow for future improvements to add e500mc
dcbz handling.

  target-s390x: Clean up cpu_inject_*() signatures

Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d947798cba92d836d06f6e017ba2b19d (s390:
I/O interrupt and machine check injection.) added functions
cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument,
claiming consistency with cpu_inject_ext().

This complicates making cpu_interrupt() take a CPUState even more and it
required to pass &cpu->env from some S390CPU-aware call sites already,
creating inconsistency elsewhere. Address that.

This also eliminates the need for CPUS390XState in s390_virtio_irq().

The user run migrate -d "exec:gzip -c > vm.gz"
The user won't be able to load vm.gz and get an error.
