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.
