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.

In debugfs cleanup patch:
[PATCH 07/14] ASoC: Intel: Skylake: Add function to cleanup debugfs 
interface

you define skl_debugfs_exit separately - its usage is split and present 
in this very patch instead. However, for tplg counterpart - 
skl_tplg_exit - you've decided to combine both together. Why not 
separate tplg cleanup too?

This is done because skl_debugfs_exit() can be introduced standalone.
However skl_tplg_exit() has code that is being moved from other places.
If I introduced it in separate commit, other one would be adding call
to this function while removing things that happen inside, losing part
of information, about the fact that code is actually just being moved.
