I feel these should be done away with if we describe hardware in DT
The compatible property can imply things like this.
But how this is structured is a bit strange. Normally you have a per
compatible struct with these as elements and the compatible matching
selects the struct.
You're right, I'll change that.

adding .compatible should be the only thing required, if at all for
this
addition :)
