ASoC: SOF: Intel: TGL: set shutdown callback to hda_dsp_shutdown
According to hardware spec and PMC FW requirement, the DSP must be
in D3 state before entering S5. Define the shutdown function to use
snd_sof_suspend as shutdown callback to make sure DSP is in D3 state.
Fixes: 44a4cfad8d78 ("ASoC: SOF: Intel: tgl: do thorough remove at .shutdown() callback")
