support the language specified by Language, then EFI_UNSUPPORTED is returned.
@param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
EFI_COMPONENT_NAME_PROTOCOL instance.
@param ControllerHandle[in] The handle of a controller that the driver

@param ChildHandle[in] 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

controller. It will not be NULL for a bus
driver that wishes to retrieve the name of a
child controller.
