Unfortunately, I see this a bit. It's convenient because the schema
passes all the checks. Doh! And I usually stare at it wondering how it
passed.

Though I probably did review this, so IDK...

There's 2 parts. There's the resolving the defines and then applying the
schema to the cells. I actually think the latter would be easier. At
least from a documenting standpoint, we just need to define our own
keyword to stick the schema under. With the tools doing dtb based
validation now, the tools already get the phandle node and get the cell
size from the DT. It's just another step to extract the
node's compatible, find it's schema, and get its cell format schema. Any
volunteers?
