memory: mtk-smi: Use a struct for the platform data for smi-common
Use a struct as the platform special data instead of the enumeration. Also there is a minor change that moving the position of "enum mtk_smi_gen" definition, this is because we expect define "struct mtk_smi_common_plat" before it is referred. This is a preparing patch for mt8183.
