On some board, the ID pin is not connected so the B session must be overridden with "u-boot,force_b_session_valid" but the VBus sensing must continue to be handle. To managed it, this patch adds a new DT field "u-boot,force-vbus-detection" to use with "u-boot,force_b_session_valid" Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
