This should have been done before removing TARGET_ALIGNED_ONLY,

When trying to run sh4 emulations with qemu 10.1.0, I get quite interesting
error messages. Bisect points to this patch, and reverting it fixes the
problem.
Actually, it is worse: Commit a4027ed7d4 ("target: Use
cpu_pointer_wrap_notreached
for strict align targets") claims that "Alpha, HPPA, and SH4 always use aligned
addresses" which just is not true. At least sh4 generates an unaligned trap and
handles the problem in the trap handler. Result is
ERROR:../accel/tcg/cputlb.c:2944:cpu_pointer_wrap_notreached: code should not
be reached
Bail out! ERROR:../accel/tcg/cputlb.c:2944:cpu_pointer_wrap_notreached: code
should not be reached
Yes, I posted a fix for this one yesterday.
