[media] v4l: vsp1: Replace .set_memory() with VSP1_ENTITY_PARAMS_PARTITION
The new VSP1_ENTITY_PARAMS_PARTITION configuration parameters type covers all registers that need to be configured for every partition. This prepares for support of image partitioning, and replaces the .set_memory() operation as the memory registers take different values for every partition.
