Patrick Delaunay 6998974926 fdt: Allow indicating a node is for U-Boot proper only
This add missing parts for previous commit 06f94461a9
("fdt: Allow indicating a node is for U-Boot proper only")

At present it is not possible to specify that a node should be used before
relocation (in U-Boot proper) without it also ending up in SPL and TPL
device trees. Add a new "u-boot,dm-pre-proper" boolean property for this.
