/************************************************************************************
* Name: board_read_VBUS_state

* Description:
* All boards must provide a way to read the state of VBUS, this my be simple
* digital input on a GPIO. Or something more complicated like a Analong input
* or reading a bit from a USB controller register.
*
* Returns - 0 if connected.
