Update ConnectController() to convert an ImageHandle retrieved from the Platform Driver Override Protocol or the Bus Specific Driver Override Protocol into a set of Driver Binding Handles. This is required if the ImageHandle produces more than one Driver Binding Handle or produces a Driver Binding Protocol on a handle other than the ImageHandle for the driver.

Locate the driver binding handle which a specified driver binding protocol installed on.
Arguments:
DriverBindingNeed - The specified driver binding protocol.
Handle - The driver binding handle which the protocol installed on.
Returns:
