ASoC: topology: Replace fake root_device with kunit_device in tests

Using struct root_device to create fake devices for tests is something
of a hack. The new struct kunit_device is meant for this purpose, so use
it instead.

ASoC: topology: KUnit: Remove now redundant non_legacy_dai_naming flag

The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

ASoC: topology: KUnit: Followup prototype change of snd_soc_unregister_card()

snd_soc_unregister_card() was recently converted to return void. Only
the first instance was adapted, so convert the remaining ones now to fix
building the topology test.

ASoC: core: Make snd_soc_unregister_card() return void

The function snd_soc_unregister_card() returned 0 unconditionally and most
callers don't care to check the return value. Make it return void and
adapt the callers that didn't ignore the return value before.

This is a preparation for making platform remove callbacks return void.

ASoC: topology: KUnit: Convert from cpu to data format

When creating topology templates and overriding data in specific test
cases it should be done with cpu_to_le32 macro, so we operate on correct
data on all architectures, as topology parser use le32_to_cpu to parse
data from structures.

ASoC: topology: KUnit: Add KUnit tests passing topology with PCM to snd_soc_tplg_component_load

In order to ensure correct behaviour of topology API, add unit tests
exercising topology functionality.

Add topology containing PCM template and tests for parsing it. Also
adds test cases simulating modules reloads in case of separate drivers
for card and component.

exercising topology functionality.

Add "empty" topology template and tests for parsing it. Also adds few

ASoC: topology: KUnit: Add KUnit tests passing various arguments to snd_soc_tplg_component_load

In order to ensure correct behaviour of topology API, add unit tests
exercising topology functionality.

Start with adding cases for passing various arguments to
snd_soc_tplg_component_load as it is part of exposed topology API.

First test case adds test passing NULL component as argument.
Following one adds test case for passing NULL ops as argument.
Finally add test case passing NULL fw as argument.
