target-arm: Minimalistic CPU QOM'ification
Introduce only one non-abstract type TYPE_ARM_CPU and do not touch cp15 registers to not interfere with Peter's ongoing remodelling. Embed CPUARMState as first (additional) field of ARMCPU. Let CPUClass::reset() call cpu_state_reset() for now. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
