    dtc: Add basic testcases for dtc
    
    This patch adds a handful of simple testcases for dtc.  It adds a dts
    file which should generate the same sample tree as is used for the
    libfdt testcases, and tests invoking dtc on this dts, plus the
    standard batch of libfdt cases on the resulting dtb, which effectively
    checks that the dtb is correct.
    
    Because the test framework assumes each testcase is an executable with
    the right output conventions, we use a little shell script, dtc.sh, as
    a wrapper around dtc itself.  It simply invokes dtc and returns a PASS
    or FAIL depending on whether dtc returned an error.
    
    It's not much, but it's a start.
