spi: dw: Add SoC-specific compatible strings

Browse Source 
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.
