ASoC: sun8i-codec: fix crash on module removal

Browse Source 
[ Upstream commit 278df5e552 ]

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.
