PATCH 1/1 ASoC: sun8i-codec: fix crash on module removal

drvdata is actually sun8i_codec, not snd_soc_card, so it crashes when calling snd_soc_card_get_drvdata().

Drop card and scodec vars anyway since we don't need to disable/unprepare clocks - it's already done by calling runtime_suspend()

Drop clk_disable_unprepare() calls for the same reason.

Fixes 36c684936fae7 ("ASoC: Add sun8i digital audio codec")
