Once u-boot's build system invokes
python3 scripts/dtc/pylibfdt/setup.py --quiet build_ext --inplace
it may fail with
scripts/dtc/pylibfdt/setup.py:40: SyntaxWarning: invalid escape sequence '\w' RE_KEY_VALUE = re.compile('(?P<key>\w+) *(?P<plus>[+])?= *(?P<value>.*)$')
depending on the used Python version.
Explicitly mark the regex string as raw string to avoid the warning.
