[PATCH v2 00/16] target: Make 'cpu-qom.h' really target agnostic

[Philippe Mathieu-Daudé]

Since v1:
- Added R-b tags
- Addressed Richard comments
- Postponed OBJECT_DECLARE_CPU_TYPE() changes

A heterogeneous machine must be able to instantiate CPUs
from different architectures. In order to do that, the
common hw/ code has to access to the QOM CPU definitions
from various architecture.

Those QOM definitions are published in "target/foo/cpu-qom.h".
All 'cpu-qom.h' must be target agnostic, so hw/ can include
multiple of them in order to create a heterogeneous machine.

This series strengthen all (except PPC...) target 'cpu-qom.h',
making them target agnostic.

For various targets it is just a matter of moving definitions
where they belong (either 'cpu.h' or 'cpu-qom.h').

For few (mips/riscv/sparc/x86) we have to remove the target
specific definitions (which 'taint' the header as target specific).

For mips/sparc/x86 this implies splitting the base target
definition by making it explicit to the build type (32 or 64-bit).

PPC is missing because CPU types are currently registered
indistinctly, and whether a CPU is 32/64 bit can not be detected
at build time (it is done in each cpu_class_init() handler,
*after* the type is registered).

Based-on: <20231010074952.79165-1-philmd@linaro.org>
  Introduce qtest_get_base_arch() / qtest_get_arch_bits()
