ASoC: simple-card: merge simple-scu-card on Doc
simple-card and simple-scu-card are very similar driver, but the former is supporting normal sound card, the latter is supporting DPCM sound card. We couldn't use normal sound and DPCM sound in same time by one sound card. This patch merges both sound card into simple-card. Now we can use both feature on same driver. simple-card is now supporting .compatible = "simple-scu-audio-card".
