V4L/DVB (13661): rj54n1cb0c: Add cropping, auto white balance, restrict sizes, add platform data

It has been experimentally found out, that the sensor only supports up to
512x384 video output and also has some restrictions on minimum scale. We
disable non-working size ranges until, maybe, someone finds out how to properly
set them up. Also add cropping support, an auto white balance control, platform
data to specify master clock frequency and polarity of the IOCTL pin.
