spi: s3c64xx: add Exynos5433 compatible for ioclk handling
The new compatible is related to the Samsung Exynos5433 SoC. The difference between the previous is that in the exynos5433 the SPI controller is driven by three clocks instead of only one. The new clock (ioclk) is controlling the input/output clock whenever the controller is slave or master. The presence of the clock line is detected from the compatibility structure (exynos5433_spi_port_config) as a boolean value. The probe function checks whether the ioclk is present and if so, it acquires. The runtime suspend and resume functions will handle the clock enabling and disabling as well.
