The fsl-mc bus discovers and exports devices dynamically allocated by the Management Complex firmware. This patch set adds the ability to automatically create a device link between a consumer device on the fsl-mc bus and a supplier one. For example, a dpni device (a network interface) requests access to a dpio device (I/O portal) using the dpaa2_io_service_register function which is enhanced to also add the corresponding device link between them. The first 3 patches set the stage for a proper handling of device links while the following 2 are the ones that add the actual links. The internal management of the links is not exported to the consumer driver, but it's rather included in the functions that actually allocate the provider device: fsl_mc_portal_allocate, fsl_mc_object_allocate and dpaa2_io_service_register.
