Guennadi Liakhovetski c41debafc6 V4L/DVB (12504): soc-camera: prepare soc_camera_platform.c and its users for conversion 
soc_camera_platform.c is only used by y SuperH ap325rxa board. This patch
converts soc_camera_platform.c and its users for the soc-camera platform-
device conversion and also extends soc-camera core to handle non-I2C cameras.
