No board is using Renesas sound driver via platform boot now. This means all user is using DT boot. Platform boot support is no longer needed. But, it strongly depends on platform boot style. This patch removes platform boot support from ssi.c Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
