fdtdec: Fix boundary check
In U-Boot, the reserved memory end address is considered as a inclusive
address. This notion is followed while adding a reserved memory node to
the DT.
For example:
end_address = start_address + size - 1
Follow the same notion and fix the end address computation while checking
for existing nodes.
