bus: fsl-mc: automatically add a device_link on fsl_mc_[portal,object]_allocate
Allocatable devices can be acquired by drivers on the fsl-mc bus using the fsl_mc_portal_allocate or fsl_mc_object_allocate functions. Add a device link between the consumer device and the supplier device so that proper resource management is achieved. Also, adding a link between these devices ensures that a proper unbind order is respected (ie before the supplier device is unbound from its respective driver all consumer devices will be notified and unbound first).
