This adds SoC-specific compatible strings to all users of the designware spi device. This will allow for the correct driver to be selected for each device. Where it is publicly documented, a compatible string for the specific device version has also been added. Devices without publicly-documented device versions include MSCC SoCs, and Arc Socs. All compatible strings except those for SoCFPGAs and some of the versioned strings have been taken from Linux. Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly necessary. However, it is a good cleanup and brings things closer to Linux.
