David Gibson c34e88354a Don't use diff to check fdt{get,put} results
Currently the fdt{get,put}-runtest.sh scripts invoke diff to check if
fdt{get,put} did the right thing.  This isn't great though: it's not
obvious from the diff output which is the expected and which is the
actual result; diff's line by line behaviour is useless here, since all
the results are a single line and finally, when there is a difference
it always prints information even when the tests are supposed to be
running in quiet mode.

This patch uses cmp instead, and explicitly prints the expected results,
when running in verbose mode (the invocation of fdtget itself will have
already displayed the actual results in this mode.
