On this specifically. I was all ready to add an additional patch to 
document this but then I noticed nothing actually uses the 
"marvell,sdhci-xenon" compatible and it appears nothing ever did. I then 
figured I'd delete the unused compatible string from armada-37xx.dtsi 
but then I remembered that sometimes we add compatible strings to have 
them "just in case" we need them for some SoC specific workaround.

So there's a few things I can do

0. Nothing (easy) although the binding I just submitted will complain 
about the unexpected value
1. Document "marvell,sdhci-xenon" as a valid compatible
1.a. Add "marvell,sdhci-xenon" to the sdhci-xenon.c driver
2. Remove "marvell,sdhci-xenon" from armada-37xx.dtsi
