[PATCH v2 00/30] single-binary: start make hw/arm/ common

[Pierrick Bouvier <pierrick.bouvier@linaro.org>]

This series focuses on removing compilation units duplication in hw/arm. We
start with this architecture because it should not be too hard to transform it,
and should give us some good hints on the difficulties we'll meet later.

We first start by making changes in global headers to be able to not rely on
specific target defines. In particular, we completely remove cpu-all.h.
We then focus on removing those defines from target/arm/cpu.h.

From there, we modify build system to create a new hw common library (per base
architecture, "arm" in this case), instead of compiling the same files for every
target.

Finally, we can declare hw/arm/boot.c, and most of the boards as common as a
first step for this part.

v2:
- rebase on top of Richard series
- add target include in hw_common lib
- hw_common_lib uses -DCOMPILE_SYSTEM_VS_USER introduced by Richard series
- remove cpu-all header
- remove BSWAP_NEEDED define
- new tlb-flags header
- Cleanup i386 KVM_HAVE_MCE_INJECTION definition + move KVM_HAVE_MCE_INJECTION
- remove comment about cs_base in target/arm/cpu.h
- updated commit message about registers visibility between aarch32/aarch64
- tried remove ifdefs in target/arm/helper.c but this resulted in more a ugly
  result. So just comment calls for now, as we'll clean this file later.
- make most of the boards in hw/arm common
