Make cpu_arm_init() return a QOM ARMCPU, so that we don't need to obtain an ARMCPU through arm_env_get_cpu() in machine init code. This requires to adjust the inclusion site of cpu-qom.h and in turn, forward-looking, to homogenize its include order. cpu_init() must still return a CPUARMState for backwards and cross-target compatibility, so adjust the cpu_init macro.
