There are several vendor-specific versions of the DW SPI controllers, each of which may have some peculiarities with respect to the original IP-core. Seeing it has already caused adding flags and a callback into the DW SPI private data, let's introduce a generic capabilities interface to tune the generic DW SPI controller driver up in accordance with the particular controller specifics. It's done by converting a simple Alpine-specific CS-override capability into the DW SPI controller capability activated by setting the DW_SPI_CAP_CS_OVERRIDE flag.
