* Name: stm32_otgfshost_initialize
*
* Description:
* Initialize USB host device controller hardware.
*
* Input Parameters:
* controller -- If the device supports more than USB host controller, then
* this identifies which controller is being initializeed. Normally, this
* is just zero.
*
* Returned Value:
* And instance of the USB host interface. The controlling task should
* use this interface to (1) call the wait() method to wait for a device
* to be connected, and (2) call the enumerate() method to bind the device
* to a class driver.
*
* Assumptions:
* - This function should called in the initialization sequence in order
* to initialize the USB device functionality.
* - Class drivers should be initialized prior to calling this function.
* Otherwise, there is a race condition if the device is already connected.
