This add missing parts for previous commit 06f94461a9f4 ("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.

...
NB: we could also remove the tags u-boot,dm-pre-reloc/u-boot,dm-spl : we
can gain place in spl dtb
These tags are not needed as binding is mandatory in SPL
build for ALL
node present in SPL device tree
others node are cleaned by fdtgrep (but impact in SPL code)
Finally I will sent a patch for this proposal (today I hope) => On my board stm32mp1-ev1, the SPL device tree is reduced by 790 bytes
FYI: patch sent with http://patchwork.ozlabs.org/patch/1039756/
NB: side effect on the patch, we only need to TAG the children (all node are bounded in SPL) That improve the next point.
After test, the phandle of the parent node is remove when the tag preloc or spl is not present.... So the need to tag all the DT tree is not solved.
