"Kernel Panic" run 'soft/kmod_scripts/sof_bootone.sh' cause kernel panic on BYT, CNL and APL #97

@zhigang-wu ok so soc_cleanup_card_resources() should also free any topology and call snd_soc_tplg_component_remove() for each component in the sound card.
@wenqingfu it's a problem for any driver who want s to modify topology at runtime. SOF is the only driver that supports this. The rest just load a static topology.

why this is a problem for SOF, not to other ASoC drivers?
