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.

Renesas RZ/N1 SPI Controller



This controller is based on the Synopsys DW Synchronous Serial Interface and

inherits all properties defined in snps,dw-apb-ssi.txt except for the

compatible property.



Required properties:

- compatible : The device specific string followed by the generic RZ/N1 string.

   Therefore it must be one of:

   "renesas,r9a06g032-spi", "renesas,rzn1-spi"

   "renesas,r9a06g033-spi", "renesas,rzn1-spi"
