Convert the Samsung SoC (S3C24xx, S3C64xx, S5Pv210, Exynos) SPI controller bindings to DT schema format. The conversion also drops requirement from providing controller-data and its data for each of SPI peripheral device nodes. The dtschema cannot express this and the requirement is being relaxed in the driver now.
