V4L/DVB (13130): soc-camera: add a new driver for the RJ54N1CB0C camera sensor from Sharp

This adds an soc-camera / v4l2-subdev driver for the RJ54N1CB0C CMOS camera
sensor from Sharp. The sensor is very picky about initialisation and
configuration sequences. The driver limits artificially maximum window size by
800x600, although the sensor supports 1600x1200. Sizes above 800x600 don't seem
to work correctly, besides, examples from the system integrator use sizes above
640x480 only for still photography. Unfortunately, I had to use "magic"
register-value pairs for undocumented and "reserved" registers. This version of
the driver also omits some functionality, like cropping, which hasn't been
sufficiently tested yet and will be added later.
