[PATCH] ASoc: SOF: Fix sof-audio-pci-intel-tgl shutdown timeout during hibernation

[Zhen Ni]

On Dell Latitude 3420 Notebook, sof-audio-pci-intel-tgl may fail to shutdown
sporadically during hibernation as following log:

[   43.281110] PM: Image saving done
[   43.281699] PM: hibernation: Wrote 2828852 kbytes in 2.78 seconds(1017.57 MB/s)
[   43.282359] PM: SI
[   43.345156] kvm: exiting hardware virtualization
[   43.345865] auxiliary snd_sof.hda-probes.0: shutdown
[   43.346359] skl_hda_dsp_generic skl_hda_dsp_generic: shutdown
[   43.346849] skl_hda_codec hdmi ehdaudio0D2: shutdown
[   43.398204] snd_hda_codec_realtek ehdaudio0DO: shutdown
[   43.419621] dmic-codec dmic-codec: shutdown
[   43.420194] sof-audio-pci-intel-tgl 0000:00:1f.3: shutdown

Call wait_xxx_timeout() to process the timeout.
