ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase1
rsrc-card which is using DPCM feature was created for Renesas sound. But not only Renesas, but many SoC can use this driver, because it is based on simple-card driver. To use it as more open driver, rsrc-card will be renamed to simple-scu-card. In order to easy patch review, as 1st step, this patch renames "rsrc" function prefix to "asoc_simple".
