ASoC: SOF: Intel: mtl: add core_get & put support on MeterLake platforms

Browse source

In core_get case, driver can power up primary core and don't need to send
ipc message to fw. Non-primary core should be powered up by fw with ipc
message.

In core_put case, driver should first send ipc message to fw to disable dsp
core then power down primary core if the target is primary core.
