dt-bindings: renesas,sh-msiof: Add MSIOF I2S Sound support
Renesas MSIOF (Clock-Synchronized Serial Interface with FIFO) can work as both SPI and I2S. MSIOF-I2S will use Audio Graph Card/Card2 driver which uses Of-Graph in DT. MSIOF-SPI/I2S are using same DT compatible properties. MSIOF-I2S uses Of-Graph for Audio-Graph-Card/Card2, MSIOF-SPI doesn't use Of-Graph. Adds schema for MSIOF-I2S (= Sound).
