* Description:
* When the USBHOST module is set to smart-standby mode, and when it is
* ready to enter the standby state (i.e. all ports are suspended and
* all attached devices are in suspend mode), then it can wrongly assert
* the Mstandby signal too early while there are still some residual OCP
* transactions ongoing. If this condition occurs, the internal state
* machine may go to an undefined state and the USB link may be stuck
* upon the next resume.
*
* Workaround:
* Don't use smart standby; use only force standby,
* hence HWMOD_SWSUP_MSTANDBY
