Most users of dw-apb-ssi use spi-{r,t}x-bus-width of 1, however the Canaan k210 is wired up for a width of 4. Quoting Serge: The modern DW APB SSI controllers of v.4.* and newer also support the enhanced SPI Modes too (Dual, Quad and Octal). Since the IP-core version is auto-detected at run-time there is no way to create a DT-schema correctly constraining the Rx/Tx SPI bus widths. /endquote

As such, drop the restriction on only supporting a bus width of 1.
