ASoC: SOF: ipc4: Ensure DSP is in D0I0 during sof_ipc4_set_get_data()

Browse source 
[ Upstream commit e51f49512d ]

The set_get_data() IPC op bypasses the check for the no_pm flag as done
with the regular IPC tx_msg op. Since set_get_data should be performed
when the DSP is in D0I0, set the DSP power state to D0I0 before sending
the IPC's in sof_ipc4_set_get_data().
