patman is no longer shipped from the U-Boot tree, so drop it from the 'make pip' target and from make_pip.sh, and remove its packaging files (setup.py, pyproject.toml, requirements.txt). Nothing else refers to them by this point in the series, so they can go. Also fix binman's pyproject.toml, which declares package-data for a 'patman' package (a copy-paste leftover); use 'binman' instead. Signed-off-by: Simon Glass <sjg@chromium.org>
