target-arm: make cpu-qom.h not target specific
Make ARMCPU an opaque type within cpu-qom.h, and move all definitions of private methods, as well as all type definitions that require knowledge of the layout to cpu.h. This helps making files independent of NEED_CPU_H if they only need to pass around CPU pointers. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
