spi: dw-apb-ssi: Integrate Renesas RZ/N1 SPI controller
Originally, the Renesas RZ/N1 SPI Controller DT bindings were not
integrated in the main DT bindings for the Synopsys DesignWare
Synchronous Serial Interface, but in its own file, as the RZ/N1
controller has additional registers for software CS control and DMA.
As so far DMA is not supported on RZ/N1, and json-schema can handle any
possible differences fine, integrate the RZ/N1 compatible values in the
main DT bindings for the Synopsys DW SSI.
