[media] V4L: soc-camera: start removing struct soc_camera_device from client drivers
Remove most trivial uses of struct soc_camera_device from most client drivers, abstracting some of them inside inline functions. Next steps will eliminate remaining uses and modify inline functions to not use struct soc_camera_device.
