ASoC: apple: mca: Do not mark clocks in use for non-providers

On the speakers PCM, this sequence:

1. Open playback
2. Open sense
3. Close playback
4. Close sense

would result in the sense FE being marked as clocks in use at (2), since
there is a clock provider (playback FE). Then at (4) this would WARN since
there is no driver any more when closing the in use clocks.

If (1) and (2) are reversed this does not happen, since the sense PCM is
not marked as using the clocks when there is no provider yet. So, check
explicitly whether the substream FE is a clock provider in be_prepare,
and skip everything if it isn't.
