Media bus configuration flags and media bus type were so far a property of each VIN instance, as the subdevice they were connected to was immutable during the whole system life time. With the forth-coming introduction of parallel input devices support, a VIN instance can have the subdevice it is connected to switched at runtime, from a CSI-2 subdevice to a parallel one and viceversa, through the modification of links between media entities in the media controller graph. To avoid discarding the per-subdevice configuration flags retrieved by v4l2_fwnode parsing facilities, cache them in the 'rvin_graph_entity' member of each VIN instance, opportunely renamed to 'rvin_parallel_entity'. Also modify the register configuration function to take mbus flags into account when running on a bus type that supports them. The media bus type currently in use will be updated in a follow-up patch to the link state change notification function.
