Hi Mark, Rob, Krzysztof
Cc Geert

Renesas MSIOF can work as both SPI and I2S.
Current Linux supports MSIOF-SPI. This patch-set adds new MSIOF-I2S.

Because it is using same HW-IP, we want to share same compatible for both
MSIOF-SPI/I2S case. MSIOF-I2S (Sound) will use Audio-Graph-Card/Card2 which
uses Of-Graph, but  MSIOF-SPI is not use Of-Graph.
So, this patch-set assumes it was used as MSIOF-I2S if DT is using Of-Graph,
otherwise, it is MSIOF-SPI (This assumption will works if SPI *never*
use Of-Graph in the future).
