From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
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 should be renamed to
simple-dpcm-card. In order to easy patch review, as 1st step,
this patch renames "rsrc" function prefix to "asoc_simple".
