[PATCH v2 04/16] spi: dt-bindings: dw-apb-ssi: update spi-{r,t}x-bus-width

[Conor Dooley <mail@conchuod.ie>]

From: Conor Dooley <conor.dooley@microchip.com>

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.

Serge, I dropped your R-b when I swapped to the default
property since it changed the enum.
