Actually dtbs_check comes up clean, but more I dug at it, looks like we
should probably cleanup.

It is all over our k3 dts folder for dma. Digging further, it looks to
have been explicitly permitted by the bindings:

$ git grep 'compatible = "simple-mfd";'  Documentation/devicetree/bindings/
Documentation/devicetree/bindings/dma/ti/k3-bcdma.yaml:            compatible = "simple-mfd";
Documentation/devicetree/bindings/dma/ti/k3-pktdma.yaml:            compatible = "simple-mfd";
Documentation/devicetree/bindings/dma/ti/k3-udma.yaml:            compatible = "simple-mfd";

Looks like we will have to cleanup the yaml bindings and the dts nodes
in a manner that doesn't break the platforms.

I am not saying that simple-mfd usage is correct, but it was
explicitly permitted by schema in these instances, are you OK that we
clean that in the upcoming merge window as the very first thing we do
and let this series through?
