precalculate_color() had a optimization that avoided duplicated
conversion for YUV formats. This optimization did not take into
consideration YUV444, YUV555, YUV565 or limited range quantization.
This patch keeps the optimization, but fixes the wrong handling.

These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very
useful format for image segmentation algorithms.

Replace is_yuv with color_enc Which can be used by other
color encodings such us HSV.
This change should ease the review of the following patches.

Hi Laurent
It is actually a very good comment. :) In our case we have implemented
the format ourselves in the FPGA and we support both 0-255 and 0-179
Hue ranges.
After some weeks of use, only the 0-179 range is used in userpace. The
reasons for this is mainly that it is the format used by OpenCV
