Subject: [PATCH v2 07/11] ASoC: Intel: Skylake: Properly cleanup on component removal
When we remove component we need to reverse things which were done on
init, this consists of topology cleanup, lists cleanup and releasing
firmware.
Currently cleanup handlers are put in wrong places or otherwise missing.
So add proper component cleanup function and perform cleanups in it.
