ASoC: SOF: remove unregister calls from shutdown

Merge series from Kai Vehmanen <kai.vehmanen@linux.intel.com>:

This patchset is an alternative solution to problems
reported by Ricardo Ribalda <ribalda@chromium.org> and
Zhen Ni <nizhen@uniontech.com>, as discussed in

- "[PATCH] ALSA: core: Fix deadlock when shutdown a frozen userspace"
 https://mailman.alsa-project.org/pipermail/alsa-devel/2022-November/209248.html

- "[PATCH] ASoc: SOF: Fix sof-audio-pci-intel-tgl shutdown timeout during hibernation"
  https://mailman.alsa-project.org/pipermail/alsa-devel/2022-December/209685.html

It was raised by Oliver Neukum <oneukum@suse.com> that kernel should
not let user-space stall the shutdown process in any scenario and the
unregister call in current SOF shutdown code is not right.

This series reverts the ASoC SOF patch to unregister clients and
the machine drivers at shutdown. To avoid bringing back old bugs,
the series includes a patch to fix S5 entry on certain Intel
platforms.
