ASoC: test-component: add set_tdm_slot stub implementation

The test-component driver implements various stub callbacks. One
of the ones it doesn't implement is set_tdm_slot. This has no
functional impact on whether ASoC core believes test-component to
do TDM or not, it just means that any TDM configuration can't
readily be dumped for debugging purposes like it can with the other
callbacks.

Add a stub implementation to allow for this. The output uses dev_info
rather than dev_dbg, to be in line with the set_fmt stub implementation
above.
