ASoC: cs35l56: Fix some cleanup memory leaks

Richard Fitzgerald <rf@opensource.cirrus.com> says:

These are for-next.

They are not urgent because it only leaks memory if the driver failed to
component_probe or is removed, which wouldn't happen in normal use.

This series fixes some memory leaks:
- The memory allocated by wm_adsp/cs_dsp was not freed.
- If component_probe() failed it didn't clean up.

The addition of this cleanup in patch #3 exposes an existing possible
double-free of the debugfs, which is fixed in patch #2.
