* Description:
* Enable/disable driving of VBUS 5V output. This function must be provided be
* each platform that implements the STM32 OTG FS host interface
*
* "On-chip 5 V VBUS generation is not supported. For this reason, a charge pump
* or, if 5 V are available on the application board, a basic power switch, must
* be added externally to drive the 5 V VBUS line. The external charge pump can
* be driven by any GPIO output. When the application decides to power on VBUS
* using the chosen GPIO, it must also set the port power bit in the host port
* control and status register (PPWR bit in OTG_FS_HPRT).
*
* "The application uses this field to control power to this port, and the core
* clears this bit on an overcurrent condition."
*
* Input Parameters:
* iface - For future growth to handle multiple USB host interface. Should be zero.
* enable - true: enable VBUS power; false: disable VBUS power

* None
