usb: fotg210-udc: Implement VBUS session
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.
