This - Protocol instance pointer.
ControllerHandle - Handle of device to test
RemainingDevicePath - Optional parameter use to pick a specific child
device to start.
Returns:
EFI_SUCCESS - This driver supports this device

Routine Description:
Stop this driver on ControllerHandle.
Arguments:

ControllerHandle - Handle of device to stop driver on
NumberOfChildren - Number of Handles in ChildHandleBuffer. If number of
children is zero stop the entire bus driver.
ChildHandleBuffer - List of Child Handles to Stop.
Returns:
