spi: dt-bindings: nxp,imx94-xspi: Document imx94 xspi 



Document imx94 xspi that supports interface to serial flash
supporting following features:

- Single-bit SPI, Dual SPI, Quad SPI and Octal SPI.
- Single Data Rate or Double Data Rate modes.
- Direct memory mapping of all AHB memory accesses to the
  chip system memory space.
- Multi-master AHB accesses with priority.
