Since commit 3b9d6da67e11 ("cpu/hotplug: Fix rollback during error-out in __cpu_disable()") it is ensured that callbacks of CPU_ONLINE and CPU_DOWN_PREPARE are processed on the hotplugged CPU. Due to this SMP function calls are no longer required. Replace smp_call_function_single() with a direct call to mvneta_percpu_enable() or mvneta_percpu_disable(). The functions do not require to be called with interrupts disabled, therefore the smp_call_function_single() calling convention is not preserved.
