ASoC: wm_adsp: Put debugfs_remove_recursive back in
This patch reverts commit acbf58e53041 ("ASoC: wm_adsp: Let soc_cleanup_component_debugfs remove debugfs"), and adds an alternate solution to the issue. That patch removes the call to debugfs_remove_recursive, which cleans up the DSPs debugfs. The intention was to avoid an unbinding issue on an out of tree driver/platform. The issue with the patch is it means the driver no longer cleans up its own debugfs, instead relying on ASoC to remove recurive on the parent debugfs node. This is conceptually rather unclean, but also it would prevent DSPs being added/removed independently of ASoC and soon we are going to be upstreaming some non-audio parts with these DSPs, which will require this. Finally, it seems the issue on the platform is a result of the wm_adsp2_cleanup_debugfs getting called twice. This is very likely a problem on the platform side and will be resolved there. But in the mean time make the code a little more robust to such issues, and again conceptually a bit nicer, but clearing the debugfs_root variable in the DSP structure when the debugfs is removed.
