This series continues cleaning target/arm, especially tcg folder.

For now, it contains some cleanups in headers, and it splits helpers per
category, thus removing several usage of TARGET_AARCH64.
First version was simply splitting 32 vs 64-bit helpers, and Richard asked
to split per sub category.

v4
--

- add two patches from Peter removing helper in non-tcg files
  20260216160349.3079657-1-peter.maydell@linaro.org
  This fixes build failure with kvm-only and xen-only builds on aarch64.
  I didn't split helper and gen_helper headers. If that really matters, it can
  be done in v5.

v3
--

- translate.h: missing vaddr replacement
- move tcg_use_softmmu to tcg/tcg-internal.h to avoid duplicating compilation
  units between system and user builds.
- eradicate TARGET_INSN_START_EXTRA_WORDS by calling tcg_gen_insn_start with
  additional 0 parameters if needed.

v2
--

- add missing kvm_enabled() in arm-qmp-cmds.c
- didn't extract arm_wfi for tcg/psci.c. If that's a hard requirement, I can do
  it in next version.
- restricted scope of series to helper headers, so we can validate things one
  step at a time. Series will keep on growing once all patches are reviewed.
- translate.h: use vaddr where appropriate, as asked by Richard.

Thanks, I've applied this to target-arm.next. Patchew says the
last patch here is the same as it was in v4, so I've copied
the R-by tags from Richard and Philippe across.

Thanks.
It's indeed the same, except patch 8 which has changes to accomodate the 
two new patches in prelude.
