ASoC: simple-card-utils: don't select unnecessary Platform
ALSA SoC is now supporting "no Platform". Sound card doesn't need to select "CPU component" as "Platform" anymore if it doesn't need special Platform. This patch removes such settings. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
