test: dm: update test for pins configuration in gpio
Add tests for new API set_dir_flags and set_dir_flags and associated code in gpio uclass. Test support for new flags GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE GPIO_PULL_UP and GPIO_PULL_DOWN. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
