Implement VBUS session handling for FOTG210. This is mainly used by the UDC driver which needs to call down to the FOTG210 core and enable/disable VBUS, as this needs to be handled outside of the HCD and UDC drivers, by platform specific glue code. The Gemini has a special bit in a system register to turn VBUS on and off so we implement this in the FOTG210 core.
