When a STM32 SPI instance offers I2S feature, two nodes are defined in STM32 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. Changes in v2: - Squash some patches in the serie to avoid dtbs check warnings on intermediate compilation steps.
