* Name: sam_usb_suspend
*
* Description:
* Board logic must provide the sam_usb_suspend logic if the USB driver is
* used. This function is called whenever the USB enters or leaves
* suspend mode.
*
* When 'resume' is false, this function call provides an opportunity to
* perform board-specific power-saving actions so that less power is
* consumed while the USB is suspended.
*
* NOTE:
* Certain power-saving operations are performed by the UDP driver when it
* enters suspend mode: The USB device peripheral clocks are be switched
* off. MCK and UDPCK are switched off and the USB transceiver is disabled.
*
* When 'resume' is true, normal clocking and operations must all be
* restored.
