fdt_parent_offset() is an expensive operation, so we'd like to reduce unnecessary calls to it.
Further, the practice of iterating up to the root if address/size cells aren't found was apparently done for Linux for compatibility with certain buggy Open Firmware implementations, and U-Boot inherited the code. The compliant behavior is to treat a missing #address-cells as 2, and a missing #size-cells as 1 -- never looking anywhere but the immediate parent of the node of interest.

It also reduces the size of the u-boot image by 216 bytes.
