[U-Boot] [PATCH 6/7] tools: fix incorrect usage of DT node unit address

[Andre Przywara]

The DT spec demands a unit-address in a node name to match the "reg"
property in that node. Newer dtc versions will throw warnings if this is
not the case.
Correct the generated unit names when U-Boot's mkimage creates a FIT
image.
