[PATCH v4l-utils v5 3/4] v4l2-ctl: subdev: Add support for the CSC API in the subdevices

[Dafna Hirschfeld]

The CSC API allows userspace to configure the colorspace,
quantization, (ycbcr/hsv)_enc and xfer_func fields when
setting the formats, so those fields are not read only
in userspace. This patch adds support for this API in
subevices.
