Routine Description:
This routine is called from AtapiFindXxxController to identify
devices attached to an IDE controller.
Arguments:
HwDeviceExtension - HBA miniport driver's adapter data storage
AtapiOnly - Indicates that routine should return TRUE only if
an ATAPI device is attached to the controller.
Return Value:
TRUE - True if devices found.
