dtc: Test and fix conversion to/from old dtb versions

This patch adds testcases which test dtc when used to convert between different dtb versions. These tests uncovered a couple of bugs handling old dtb versions, which are also fixed. Signed-off-by: David Gibson [EMAIL PROTECTED] Index: dtc/tests/run_tests.sh

dtc: Strip redundant name properties

If an input device tree has name properties which are correct, then they are redundant (because they can be derived from the unit name). Therefore, extend the checking code for correctness of name properties to remove them if they are correct. dtc will still insert name properties in the output
