+ Retrieves a Unicode string that is the user readable name of the controller

+ support the language specified by Language, then EFI_UNSUPPORTED is returned.
+
+ @param This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
+ EFI_COMPONENT_NAME_PROTOCOL instance.
+ @param ControllerHandle The handle of a controller that the driver
+ specified by This is managing. This handle
+ specifies the controller whose name is to be
+ returned.
+ @param ChildHandle The handle of the child controller to retrieve
+ the name of. This is an optional parameter that
+ may be NULL. It will be NULL for device
+ drivers. It will also be NULL for a bus drivers
+ that wish to retrieve the name of the bus
+ controller. It will not be NULL for a bus
+ driver that wishes to retrieve the name of a
+ child controller.
+ @param Language A pointer to a Null-terminated ASCII string
+ array indicating the language. This is the

+ Language from the point of view of the driver
+ specified by This.
+
+ @retval EFI_SUCCESS The Unicode string for the user readable name in
