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.

Ignore MSIOF-I2S case (= Of-Graph) in MSIOF-SPI Doc.
