Firmware may do context saving before powering off primary core, so driver
needs to send ipc msg by set_core_state. In IPC4 path, firmware needs to
save current context to IMR before powering off primary core. Firmware
does nothing for set_core_state message in IPC3 path. So IPC4 and IPC3
can share the same operation sequence.
