V4L/DVB (9241): soc-camera: move sensor power management to soc_camera_platform.c

Switching sensors on and off is now done by sensor drivers themselves,
typically using platform-provided hooks. Update soc_camera_platform.c to
do the same. Also remove a refundant struct soc_camera_platform_info
definition from soc_camera_platform.c.
