Current FSI got each PortA/B parameter by porta_flags/portb_flags from platform. And .set_rate function was shared for PortA/B. This structure was not readable and not flexible. This patch adds sh_fsi_port_info, and its own settings was added on each platform. it is preparation for DMAEngine support Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
