CONFIG_HAVE_ARM_SCU only gets selected if CONFIG_SMP is selected in an OMAP system, however AM43XX needs this option regardless of CONFIG_SMP and also for an AM43XX only build as it is important for controlling power in the SoC. Without this we cannot suspend the CPU for SoC suspend or cpuidle. The ARM Cortex A9 needs SCU CPU Power Status bits to be set to off mode in order for the PRCM to transition the MPU to low power modes.
