First off, this is wrong.  In the code (see drivers/core/ofnode.c and
drivers/core/util.c) everywhere we check for u-boot,dm-spl we've already
checked for u-boot,dm-pre-reloc and returned true.  So all of these kind
of changes above need to be fixed.

Second, where are you seeing that we need these nodes to be moved to be
available earlier?  Thanks!
