module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

ASoC: SOF: core: Add fw, tplg and ipc type override parameters

The different bus type helpers define their own override parameters for
firmware name/path, topology name/path. sof-pci-dev covers all while others
just a subset.
There is no technical reason to do that since these are generic platform
independent parameters.

Add the override module options to core (snd-sof module) and update the
description for the device helper modules as deprecated.

ASoC: SOF: core: Implement IPC version fallback if firmware files are missing

If a firmware file is missing for the selected IPC type then try to switch
to other supported IPC type and check if that one can be used instead.

If for example a platform is changed to IPC4 as default version but the
given machine does not yet have the needed topology file created then we
will fall back to IPC3 which should have all the needed files.

Relocate the sof_init_environment() to be done at a later phase, in
sof_probe_continue().

This will only have changes in behavior if
CONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE is enabled (Intel HDA platforms) by
not failing the module probe, but it is not going to be different case
compared to for example failed firmware booting or topology loading error.

which cannot be pushed to a workqueue. Introduce 2 new optional
callbacks.

probe_early is called before the workqueue runs. remove_late may be
called from the workqueue if load is unsuccesful, but will otherwise
be called on module unload.

ASoC: SOF: core: Free the firmware trace before calling snd_sof_shutdown()

The shutdown is called on reboot/shutdown of the machine.
At this point the firmware tracing cannot be used anymore but in case of
IPC3 it is using and keeping a DMA channel active (dtrace).

For Tiger Lake platforms we have a quirk in place to fix rare reboot issues
when a DMA was active before rebooting the system.
If the tracing is enabled this quirk will be always used and a print
appears on the kernel log which might be misleading or not even correct.

Release the fw tracing before executing the shutdown to make sure that this
known DMA user is cleared away.
