ASoC: SOF: Intel: Split the set_power_op for IPC3 and IPC4
Suspending to S0iX with IPC3 requires the PM_GATE IPC to be sent again
to stop the DMA trace. But with IPC4, this is not needed as the trace is
stopped with the LARGE_CONFIG_SET IPC. Also, sending the MOD_D0IX IPC to
set the D0I3 state again when the DSP is in D0I3 already results in an
imbalance in PM runtime states in the firmware. So split the
set_power_state ops for IPC3 and IPC4 to avoid sending the MOD_D0IX IPC
when the DSP is already in D0I3 with IPC4.
