Patrick Delaunay 5739ef2bcb usb: dwc2: add "u-boot,force-vbus-detection" for stm32
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"
