ASoC: fsl: imx-card: Skip sysclk reset for active DAIs in shutdown

In a full-duplex setup, when one direction (playback or capture) is
closed while the other is still running, imx_aif_shutdown() was
unconditionally calling snd_soc_dai_set_sysclk() with rate=0 for all
cpu/codec DAIs, which would disable the clock still needed by the
active stream.

Add snd_soc_dai_active() checks before clearing sysclk so that only
truly inactive DAIs have their clocks reset.
