This commit fixes all the E305 errors. They were found by running "flake8 ." from the root directory. This is an error defined by "pycodestyle", and has no functional impact to the source. This is simply fixing whitespace as defined by CHIPSEC's .flake8 configuration. background: https://www.flake8rules.com/rules/E305.html https://pycodestyle.pycqa.org/en/latest/intro.html#error-codes:~:text=after%20function%20decorator-,E305,-expected%202%20blank versions: flake8 v7.2.0, python v3.12.6 Signed-off-by: William Leara <william.leara@dell.com>
