arm: dt: vcm30_t124: otg: allow host gadget change

vcm30_t124 based platforms don't physically use a OTG connector that allows for
ID pin based state changes.  Since SW based transitions use ID/VBUS changes
simultaneously, allow OTG to switch directly between HOST and DEVICE modes
without needing to go through a SUSPEND state.
