dt-bindings: spi: Add realtek,rtl9301-snand 



Add a dtschema for the SPI-NAND controller on the RTL9300 SoCs. The
controller supports
 * Serial/Dual/Quad data with
 * PIO and DMA data read/write operation
 * Configurable flash access timing

description:

  The Realtek RTL9300 SoCs have a built in SPI-NAND controller. It supports

  typical SPI-NAND page cache operations in single, dual or quad IO mode.
