The DM37 and OMAP35 Torpedo share a few files, but both of them
can be migrated to OF_UPSTREAM with a small update to their
respective u-boot.dtsi files to address changes made the aliases.
Both defconfigs need to properly point to the upstream directory
structure for the device trees.  With those updated, the U-Boot
device tree files can be deleted.
