Given it is a whole hierarchy of nodes, might be cleaner if u-boot
removes the whole sub-tree of disable nodes.

This should also contain the SoC compatible. Please add this to where
that is defined instead of a new file.

Don't use '_' in node names. Building with W=2 will tell you this. You
chould build with W=1 and fix any warnings this file adds.

All these under a 'partitions' node is preferred.
