[PATCH 05/18] target/arm: Move CPU QOM type definitions to "hw/arm/cpu.h"

[Philippe Mathieu-Daudé]

Units including "target/arm/cpu.h" can't be built once via meson's
softmmu_ss[] source set. Since this header depends on specific
definitions such the word size (32 or 64-bit), for ARM such units
must go to the per-target arm_ss[].

We want to expose few architectural definitions to hardware models.

Start by exposing the ARM CPU QOM types to files under hw/
via the new "hw/arm/cpu.h" header. Doing so, less HW models
will require access to "target/arm/cpu.h".
