[media] vimc: Subdevices as modules
Change the core structure for adding subdevices in the topology. Instead of calling the specific create function for each subdevice, inject a child platform_device with the driver's name. Each type of node in the topology (sensor, capture, debayer, scaler) will register a platform_driver with the corresponding name through the component subsystem. Implementing a new subdevice type doesn't require vimc-core to be altered. This facilitates future implementation of dynamic entities, where hotpluging an entity in the topology is just a matter of registering/unregistering a platform_device in the system. It also facilitates other implementations of different nodes without touching the core code and remove the need of a header file for each type of node.
