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).
