ASoC: meson: aiu: fix duplicate debugfs directory error
Merge series from Heiner Kallweit <hkallweit1@gmail.com>:
On a S905W-based system I get the following error:
debugfs: Directory 'c1105400.audio-controller' with parent 'P230-Q200' already present!
Turned out that multiple components having the same name triggers this
error in soc_init_component_debugfs(). The proposed solution allows
other drivers to adopt the same approach with minimal effort.
With the patch the error is gone and that's the debugfs entries.
