[PATCH 3/3] ASoC: SOF: Intel: tgl: unify core_put on IPC3 & IPC4 path

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

From: Rander Wang <rander.wang@intel.com>

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.
