On this specific point. Was your intention to allow just the 
"marvell,armada-8k-nand-controller" compatible?

I made it a list as the existing usage is `compatible = 
"marvell,armada-8k-nand-controller", 
"marvell,armada370-nand-controller";` but an earlier comment you made 
suggested that your intention was to allow just the 8k compatible on 
it's own. Looking at the driver it doesn't do any is_compatible() checks 
so I don't think it cares (currently).
