When a SPI instance offers I2S feature, two nodes are defined in SoC device tree to support both SPI and I2S. Merge SPI node and I2S nodes into a single node, to avoid hardware description duplication and compilation warnings. spi2sx label is used to identify the SPI instances which are supporting I2S feature.
